Took the test today, the coral reef was very helpful but the redrock was really complicated, hope I’ll pass inshallah even though time wasn’t enought I missed solving the last cae😭
I completed the McKinsey Solve Game today! The games I got - Ecosystem Red Rock 1) Ecosystem - Got the mountain terrain Was super difficult, The process I chose was the same - - Select brackets(3) of producers - Eliminate producer brackets, for which even one producer has no consumers. - Then select one bracket from the two left. - Then start filling the animals. - Check which animals satisfy the conditions and which don't. (Calories needed should be 0, Calories provided should not be 0) - If the bracket you selected does not work, move to the other bracket. This approach helped me solve the entire ecosystem. P.S- The first bracket I selected did not work, had to pivot to the other one, with just 10 minutes to go :( Added my final animal at the last minute. This was definitely super stressful. But I think I did well by the end. 2) Red Rock - Investigation phase - Added all data points available - Don't skip on any - Analysis - Go back to the investigation phase whenever needed, do not hesitate to switch - Use the calculator to show that you are active on the screen, avoid calculating on notes, or personal calculator - Drag and drop is time-consuming, I simply typed in the data points. - Report - Was the simplest phase - Pretty straightforward - Please note, that you cannot go back to the investigation phase from the report phase. - Cases - Simply use your math skills - Learn how to do percentage calculations quickly - Read the question twice before attempting, most of the questions are tricky. Can be solved easily. Final remarks - Go through RU-vid videos, multiple times. I used the following links, which was super helpful. - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IAThTjf31S0.html - Thank you PrepMatter for this valuable resource. If you have the money, purchasing simulations sold by various vendors would be helpful. I did not buy the same. Finally, I am still waiting for the result, will make edits as I get to know.
@@Prepmatter 12:27: why shouldn't we check for all four parameters for the animals and then minimize the animals that dont satisfy the chosen location's conditions. This would help eliminate more animals, narrowing down our list to choose from. Also, this would remove the possibility of us finding out at the end that a given animal doesnt meet the location conditions. What would be the disadvantages of this approach?
If there are 3 sets of temperatures and elevations, is it possible to create a sustainable ecosystem in each of these regions, because I believe that you selected the region randomly.
Hey, I have a quick question on 21:37. The question is asking us to analyze BETWEEN December and April, but you include december in your analysis. I'm just a bit confused bcs I initially thought that the word 'between' means that we need to exclude December and April on our calculation (i think it'll be more suitable if the questions ask us to analyze FROM December TO April).. looking forward to your answer.. thanks
Thanks for your question! In a business context, 'between' two time periods includes both periods. For example, if we need to analyze how a company performed between 2020 and 2023, we examine the financials of 2020, 2021, 2022, and 2023. Hope that clarifies things!
I liked the video too much. It was really very helpful. I am wishing to practice more on game simulation, but honestly I'm out of money right now. Any suggestion?
Oh, that's a method we always use to calculate the percentage difference. For instance, if we want to determine how much higher 120 is compared to 100, we divide 120 by 100, which equals 1.2 or 120%. However, we can't say 120 is 120% higher than 100. Therefore, we subtract 1 (or 100%) from 1.2 (or 120%), resulting in 0.2 or 20%. Thus, 120 is 20% higher than 100. Hope this helps!
That's right! As I was drawing the ecosystem, I forgot to draw an arrow from shrimp to red moss (thanks for pointing it out!). But I've factored this into our calculations, and hence, the ecosystem is sustainable!
Yes, that would work well too! There are many other possible variations. Feel free to explore our interactive simulation to practice with different environments, including a coral reef and a mountain ridge scenario!
@@felixcristiano759 I went for the 5 animals as follows (in eating order): (1) Blue Jelly fish, (2) Loggerhead Sea Turtle, (3) Lanternfish, (4) Shrimp and (5) Sea Urchin… plus the 3 producers… (6) Red Moss, (7) Sea Fan, (8) Sea Lettuce.
That’s the demo version so that you’re familiar with the interactive nature of the game. Once you’re enrolled in the course, you’ll have access to the full game!
Thanks for pointing this out. Indeed, shrimp also consumes red moss. As I was drawing the ecosystem, I forgot to draw the arrow from shrimp to red moss. Yet, I've factored this into our calculations.
@@АлександраЗолотарева-о9ь because the remaining calories from it's food source; red moss & sea lettuce, are equal (1500 each after Blue Jellyfish's consumption). Part of the eating rule states that if the calories provided by the food sources are equal, then the predator eats equally from the food sources.
Timestamp 37:24 The question asks, “… if the realistic scenario is realised for all 3 activities”. If this was the case, the likelihood would be irrelevant altogether and a total of 8 + 5 + 4 = 17 species would have been saved. The question should have put the Likelihood percentages given below each graphs into context and how it relates to the animals saved.
Yes, I agree. The wording implies that we shouldn't calculate the expected value (which by the way would include the other scenario) but simply add the species saved as the likelihood is made irrelevant.
For Redrock Study, case #3. Why did you multiply the expected number of species by the likelihood of realistic outcome? The question asks "... if the realistic scenario realizes for all three activities?" So, considering it is given to us that realistic scenario is being realized, we do not need to include a probability of it.
At 10:04, wouldn't it be strategically better to remove sea urchin from the ecosystem rather than spadefish? Ceteris paribus, spadefish consumes less and the sea fan will have extra calories in its reserve for future consumption by other animals?
Took the McK Solve today. Your methodology for the ecosystem game was spot on. I got the ecosystem right on my first try triple checked everything, and still submitted with 15 minutes to spare. I spent too much time on the first section of RedRock and had only 12 minutes for the 6 questions in the second section. Was able to finish but was not able to double check the 6 case questions. Follow his method for ecosystem game and you will be fine. For redrock, practice time management skills.
12:27 Please, why did you first pick out all your species only based on one monitor(depth level); before going back to make sure they align with other monitors (salt, temperature etc) Considering that we don't have so much time to work with, I feel it would have been better to choose all that in the beginning. What you think?
the game allows you to only see 4 monitors at a time so he choose the 4 significant one and that will change over other variables since the number of species are a lot he only scheem through them cheking the significant monitor and after selection he check for the other monitors it for time management

Hey! One question with regards to Question 2 (Redrock Study): You have calculated the percentage change. However, the question was about the percentage POINT change. My approach: for summit depth --> (47-10)/10 = 370% for base depth --> (35-8)/8 = 337.5% Therefore, the percentage POINT difference is 370% - 337.5% = 32.5%
question, at timestamp 9:10 why did we remove spade fish and not sea urchin? since sea urchin has a higher calories to consume, wouldn't it be better to keep spade fish?
In the Redrock Study, Question 4 of the Analysis, why is the percentage difference calculated the way you did? I would think it is more ((summit-base)/summit)*100%
Hi @prepmatter - thanks for this video. I think there may be a mistake in Question 1 of the Redrock study: The question asks for the difference in SNOWFALL DAYS between the month with the highest AVERAGE SNOWFALL and the month with the lowest AVERAGE SNOWFALL. Doesn't that mean we need to look at the two months with the highest/lowest AVERAGE SNOWFALL and THEN calculate the difference in SNOWFALL DAYS between those two months?
I'm confused why "the month with the least average snowfall" is November (0.3mm) and not May (0.0mm)? Is it because May had 0 snowfall days which means the average would be a division by zero hence undefined hence incomparable?
no, you can calculate it like this: 23 * x% = 19 and we want to find x%, therefore: x% = 19/23, which is ~82.6%. The reduction is 1-0.826 = 0.174 AKA (1 - 19/23) = (23-19)/23 = 4/23 = ~17.4%
Are the answers automatically stored in the research journal or do we need to drag them after answering each question? Also, the description for each answer is added automatically or do we need to add it ourselves for reference?
Yes, your answers are automatically dragged (thankfully!), but you are expected to manually drag other data points into the research journal on your own.
Just took the test for a position in Lima, Peru and got a 3rd game called Sea Study (can't really remember) about combining microbes (each with 3 numeric characteristics and 1 trait) to to design treatments for 2 contaminated sites. Heads up for anyone taking the Solve in the upcoming days!!! my recommendation would be to have a range of values as you will have to average them later.
Hi! Great Video! Just had a question in the ecosystem game when we start building the food chain, here once you add the first layer of animals and form a sustainable food chain up till that layer and then proceed to add the turtle layer on top and then you check independently just that when the turtle eats does its food source die or not. But shouldn't we check for the entire food chain starting from those species with the highest calories provided and then proceed sequentially to check the sustainability of the food chain? Edit : I know that it works out perfectly in this example, but will it always work out ?
how do you hover around and select the point for the location? what factors to consider there or do you just randomly select any point and then see it parameters (like depth etc)?
you made it look easy, but when I took the assessment today I struggled regardless xD. Great content helped a lot but I guess I will need more practice!
Is this Red Rock example a real McKinsey Solve version, or very closely similar? I am subscribed to another prep site where they offer a simulation game for Red Rock that appears to be much harder than the example here, and also requires somewhat more complex math. There are 10 cases, and I always run out of time despite finishing the study in less than 20min. Is this video a more accurate representation of the difficulty of the game? If so, I'm much less daunted by this, than the simulation I'm practicing with!
And another question: is the real Red Rock game thematically similar, ie following nature/environmental topics? The simulation I'm using includes other industries, from aviation to retail.
Yes, this simulation is a good representation of the real-life assessment. In fact, we’d say the real-life assessment is even easier. Since last year, Redrock Study has reduced the number of cases from 10 to 6. The other resource you have might be outdated. And yes, you should expect ecosystem-related cases in the real-life assessment.
Hi, I have had test yesterday and got invitation to PEI. I made ecosystem task in 18 minutes. I had to change some initially chosen participants, which made me feel nervous. But I managed to change them fastly. Thank you so much for your tutorial.
Thanks for your question; shrimp consume both sea lettuce and red moss actually (as you can see at 07:30 and 09:34). As I was drawing the ecosystem, I just forgot to draw an arrow from shrimp to red moss (thanks for pointing it out!). But I've factored this into our calculations, and hence, the ecosystem is sustainable!
Awesome job explaining 🤝 Thank you 🤗 I hope I can use the knowledge gained to Ace my test tomorrow PS: I am definitely sending you a connection request😄
9:42 URGENT PLEASE ANYBODY🥺 How did you arrive at 775 for each?? I thought the arithmetic will be something like = 1450/2 = 725, then 3000 - 725 from each of the producers. Leaving them with 2275??
No, 1500-725, based on the current calories provided not the initial calories provided, Blue Jelly Fish had already taken 1500 from Red Moss and Sea Lettuce remember?
Wouldn't it be safer if we removed the Sea Urchin instead of the Spadefish? They both provide the same calories, but the Spadefish requires less calories so it would eat less of the Sea Fan?
In the ecosystem, wouldn't it be safer if we removed the Sea Urchin instead of the Spadefish, considering the Spadefish requires less calories so it would eat less Sea Fan?
In the ecosystem game, what do you recommend to do if we already formed a food web but one of our animals doesn’t comply with the region we selected (ie. different salinity level, different current level, etc)
The actual game shouldn't be too tricky. Typically, if species meet 1 or 2 criteria in the chosen location, they almost always fulfill the other requirements.

I have another inqury, should shrimp also get consumed for the system to be more sustainable or is it okay if one species or two are only consuming calories but not consumed as you pointed out on the diagram? In the shrimp case, for example and to elaborate, no other species has any sort of a connection for the shrimp to be consumed unlike the sea urchin where at least it can be eaten by the sea turtle. Thanks in advance@@Prepmatter
I took the Game solve this week. And wow your method for the ecosystem worked out! I was able to get through it quickly. Thanks a lot for this! The Reddrock game was a bit confusing my advice- understand the research thoroughly, manage your time effectively practice your maths percentages. This video is the best to get you ready for the game solve. Thank you Denz, keep up the great work!
Hello! Fantastic and informative video; thank you so much! Question for you: Is it important to show all calculations on the calculator in order to get the highest score? For me, doing 170-150 is easy mental math, as is converting .39 to a percentage. Is it ok to just do that in my head, or do you advise using the calculator for everything? Thank you!
In this video, we wanted to play it safe and use the calculator every time since the assessment evaluates the candidate’s behaviour. However, we don’t think it would be an issue to perform simple calculations mentally or by pen and paper.
Why, in the task about summit depth and base depth (40:25 min), was it originally about April, but then the number 16 was taken from April and later switched to May? The result sheet at the end shows 'May 5+3,' but 5 is a result for May, not April.
How close is this simulation to the actual game? Can anyone who has taking the test recently comment on the resemblance of the simulation for the actual game?
For the ecosystem game I got another working solution. Please let me know if I'm wrong. Great White(6000,4250) - Green Sea Turtle(4400,3000) - Lanternfish(3300,2700) - Shrimp(2750,1450)-(feeds half and half on Sea Lettuce and Red Moss) and Spadefish(2100,2400)-Sea Fan(3500)
Thank you for the content! By following your tips, I was able to finish ecosystem task with enough time to triple check calculations. For Redrock, I definitely needed to do more practice questions. Hopefully in less then two weeks I will get a response from the firm.
At 28:44, shouldn't the difference in snow depth at summit between Dec and Apr should be just 42-10=32. There is no mention of difference in 'highest' and 'lowest' snow depth.
I completed the McKinsey Solve Game. I think it went O.K. The ecosystem to be made was situated in Coral's Reef. I used an Excel file to complete this task. People who: 1. Regularly use Tab + Alt to switch between applications 2. Can type at a solid pace might find my strategy interesting. My strategy was the following: Utilize a pre-made Excel file with as many sheets as there are producer buckets (i.e., '3'). I called these possible buckets A, B and C. So the sheets are named (Coral A), (Coral B), (Coral C). Depending on which test bucket (A/B/C) I chose, I could switch to the correct sheet. This avoids that I have to work on the same sheet, which can be cumbersome if you have picked 2 buckets (based on the rule thumb) that didn't offer a solution (Unfortunately, that happened to me) In Coral A I preliminarly created a table of producer information (9 rows, because there are 9 producers), with only the following fields: Name, Depth, Temperature, Calories Provided. The Depth & Temperature automatically copies to the respective cells of the same bucket. This whole table automatically copies to sheets Coral B & Coral C. Some advice here would be to first skim through each producer and check if there are predators. If that is the case, you can ignore that particular bucket with the corresponding depth-temperature combination. It saves you some time. Also, I gave them some unique identifier (e.g.: P1, P2, ...), as such that I don't have to write the full name of the animal on paper when testing the ecosystem. Then I switched to the animals, for this I also dedicated a table with 10 rows in each sheet (10 rows for 3 sheets = 30 animals), with the following fields: Name, Depth, Temperature, Calories Needed, Calories Provided, Food Sources (full names of Animals). Correct Depth & Temperature already is copied to this table in each sheet. Also a good practice is to give the animals an unique identifier (e.g.: A1, A2, ...) for the same reason as producers. So, I saw a lot of participants that got lucky by simply applying the rule of thumb (i.e., picking the bucket with the MAX Calories Provided), which means they found a feasible solution with their first test bucket. Often, this rule of thumb can also be completely useless. In my scenario, I applied the rule of thumb and after two test buckets I didn't find a solution. However, I still managed to finish the test with 15 minutes left with a feasible solution in my last test bucket. These are my general tips: A. When filling in the information in the Excel for animals, take a good look at the information and skim through it. What do you see? Work from bottom-up, and first identify animals (2/3) that eat the producers. Take a good look at those particular animals while filling in information. In this way, I managed to see that there wasn't going to be a solution for the first test bucket. I saw red flags, such as 2 animals that had a ridiculous amount of calories needed (>6000), predators of producers that just were not going to survive, because the producers didn't offer them the necessary calories. B. To be prepared for worst-case scenarios, utilize the mock simulation of (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8hVER88E7ng.html) along with the Excel file and set a timer of 35 minutes to finish the task. If you don't make it, reflect on where you can do better and where you can manage time more efficiently. This is what I did. I also found a very useful video that really provides the exact interface that you will see when playing McKinsey's game. Can be helpful if you want to forecast situations: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IAThTjf31S0.html. Concerning, the RedRock study. The questions (4) and cases (6), were really simplistic. However, I must note that you should have a lot of attention for detail and manage your time efficiently. Read the questions twice! (each word matters). Use the tutorial time (not included in the 35 minutes) to read the instructions. I think the phase where it becomes tricky, is when calculating the answers and dragging it to the journal on the right-hand side. When filling in the answers and continuing from Analysis to Review phase, the application automatically saved the answers in my journal (I lost time because of this, since I thought I had to do it myself). If you do not have a lot of time to play around with the drag boxes, please do not hesitate to get pen & paper and write down necessary computations that you don't want to lose. This is important for the reporting phase, because there might be data that you need to fill in, that wasn't part of the Analysis phase. Very odd, but I screwed up with the graph selection. I had to plot a quantitative (discrete/continuous) variable (e.g. number of plants on RedRock) against a time-series dependent variable, so clearly they wanted me to plot the evolution of the number of plants. In this case, a bar chart offers a better perceptual accuracy, but once you choose one graph you cannot go back (that's where I screwed up). I had 3 minutes left to finish the 6 cases, but I managed to finish 3 of them quite easily. Important that you have a basic sense of: - Percentage point differences - Probabilities (Bayes, Independent vs. Dependent events, Addition or multiplication of probabilities, etc.) - Know what these statistical concepts are: median/mode/average - Weighted Average Overall, if the interface for the RedRock study would be more user friendly, you could easily finish this within 35 minutes. It's really the fact that there are small things, trying to distract you. I hope this overview is meaningful. Good luck to everyone!
@@sakshipal2680The storyline is regarding an objective to increase the # of plants by 30%, so they rolled out a three-step-plan with each step attempting to increase the amount of plants on the RedRock island. First and foremost you should calculate percentages, since it is not straightforward. Plants are divided into three subcategories (forgot the names) and for each of these subcategories they gave the number indicating how much they appear on the island. Now the physical location of the island is also divided into three locations where these plants (i.e., subcategories) reside, so ideally you could make a cross-table (plant category against location) with the cell values being the number of plants in a certain location. I am afraid the storyline varies from applicant to applicant (i.e., it is completely random).
Such a great video. I managed to do the ecosystem game well on my first try with 6 minutes to spare. Follow the method with a pen and paper and calculator, no need for the excel spreadsheet. As for the RedRock study, I just about finished it, but the time management for the cases was quite tricky. Some questions did shock me a bit, but they were simple after I got over the initial panic. Just wanted to thank this guy- regardless of outcome I feel satisfied I did the best I could watching this video :)
I believe you're referring to the actual assessment. After completing the ecosystem creation game, you are presented with animations featuring 3 animals, selected at random. This does not necessarily mean that only 3 animals survived :)
@@putrinareswarisularno3297 I’ve taken that test and I’m currently waiting for interviews:) (If I did everything correctly) Feel free to ask about anything that comes to Your mind;)
@@Pac-yr5zv Is the game presented in the video looks the same as the actual assessment? as well as for the ecosystem game, do you recommend choosing the location monitor first or building the food chain first? Thank you
why would sea urchin consume sea fan entirely, when it derives some of its caloric needs from sea lettuce? you should've clarified this part in the video
Yes, there’s no live feedback in the real life game unfortunately. But how do you think you performed? Hope you took all the time you need to double check your ecosystem.
So I just watched the entire video for the second time and I must say I feel less pressure and it is clearer now. Just need to brush up on the Redrock Study.... It's a tough one
Question, at first you said since Blue Jellyfish eats Red Moss and Sea lettuce, we have to assume it eats equally from both, so 1500 each. Why when you are analyzing what Sea urchin will eat, which eats Sea Fan and Sea lettuce, you just take all the calories it needs from one source (Sea Fan) and not considering it taking the 775 calories left from the Sea Lettuce also? Why it is eating the 3000 straight from the Sea Fan? Thanks @prepmatter
Hello. For choosing the location in the ecosystem creation game, what motivated you to choose the location with >100 depth range. Was this just a random decision? I'll like you to guide me on what to think about before choosing a location, both in the coral reef scenario and mountain ridge scenario. Thank you for this video. It's very helpful!
Alright thanks for the response. Also, Sea Urchin and Spadefish had the same calorie provided (2100), with the same food source (Sea Fan) which had 3500 as calorie provided. Then you mentioned, since they both had the same calorie provided, they'd have to consume the food source (Sea Fan) equally. However, Sea Urchin and Spadefish had two different values for their calories needed. Sea Urchin has 3000, and Spadefish has 2400. How did you do the calculation to determine that Spadefish wasn't fit for the food chain? Because from my calculation, If you divide Sea Urchin's calories needed into two (3000÷2 = 1500), then subtract it from Sea Fan's Calorie provided (3500-1500 = 2000). Then do same for Spadefish which has 2400 as calories needed (2400÷2 = 1200). Then subtract it from Sea Fan's remaining calories provided (2000-1200= 800). It shows that there will be 800 calories provided left for Sea Fan which doesn't kill it. So why was Speed fish still removed? I will appreciate your explanation. Thank you.
@@Prepmatter "Calculate the difference between the two values, divide by the average of the two values, show that as a percentage", which is what I got when google it. Seems not as the way as you did. Please let me know if I am wrong.
@@Prepmatter @28:33: you used (Bigger - Smaller)/Smaller Could you please explain the why you didn't divide by the bigger number i.e. why is the difference relative to the summit and not the base?
Thank you for this! Could you please tell me why we use 27 as the division base instead of 37 (22:50 time stamp) for the snowfall percentage difference question? Would appreciate a prompt response!
Sure, because the question asked summit to base ratio. So it should be (summit-base)/base. Let me illustrate with an example. If I ask how much higher 12 is compared to 10 in percentage, you'd do (12-10)/10, so 20% higher. I know it's trickly, but hope that helps!
The rule is a species with the highest calories provided eats first so on your final diagram on the ecosystem puzzle the great white shark eats the laggerhead seat turtle first which breaks the ecosystem because the laggerhead sea turtle will be eaten before it consumes blue sea turtle and sea urchin, please this is a humble question can someone answer. am I right am preparing for the game
You are right on the first part. The shark (6.000/4.250) eats first, leaving the sea turtle with (4.400-4.250=150/4.350). Therefore, the sea turtle survives. However, it seems like the whole approach is misleading/ incorrect. IF I AM NOT MISTAKEN HERE. My question is: After the shark, the blue jellyfish will eat, bc he has the second highest cal provided with 4.500. BUT who will eat after the jellyfish? The shrimp bc he provides 2.750 cal OR the sea turtle bc originally he provided 4.400 cal. I assume it should be the shrimp, the animal with the highest provided cal at the particular time in order. If so, the ecosystem should survive.
Somebody else asked the same question, sharing below the answer of another user: no, you can calculate it like this: 23 * x% = 19 and we want to find x%, therefore: x% = 19/23, which is ~82.6%. The reduction is 1-0.826 = 0.174 AKA (1 - 19/23) = (23-19)/23 = 4/23 = ~17.4%
There is some confusion in the Eating Rules under guidance. Timestamp 3:00 I would recommend the following changes in the wording: Para 1: The species with the highest “Calories Provided” eats first…. The animal eats its “Food Source” with the highest “Calories Provided” in the first instance… providing that the “Calories provided” of the prey satisfies the “Calories needed” of the respected Animal. If the Animal is feeding on multiple sources of food, AND they ALL provide equal amount of calories (e.g. Sea Lettuce providing 3000 cal. and Red Moss providing 3000 cal.), then the Animal will eat both prey equally… e.g. 1,500 cal. from each. Para 3: Then the species with the next highest “Calories Provided” eats in the Ecosystem…. If there is a tie between “Calories Provided” for the Animals (e.g. Sea Urchin providing 2,100 cal. and Spadefish providing 2,100 cal.), then no Animal will take priority as the “primary eater” and will therefore split their food source equally. E.g. Sea Urchin and Spadefish both eat Sea Fan, they would fulfil their calorie need by utilising 50% of the prey’s “Calories Provided”. This information is given at Timestamp 9:46 but not included in the Eating Rules under guidelines, or at least clear enough.
Since your cursor/keyboard activities are also monitored, whenever possible, we advise to use the calculator provided in the game. Also, you can drag datapoints from the research journal to the calculator, and hence, you can avoid making mistakes by using the calculator provided.
Is it possible to copy and paste text in the REAL Redrock test? Can you select and copy text from the questions and paste it elsewhere, or is the screen locked down to prevent copying?
10:08 Thanks alot!!! I don't understand why Spade Fish was removed. Isn't it true that the ecosystem would survive even if Sea Urchin, instead of Spade Fish, was removed? If that's the case, the remaining calories for the Sea Fan would be 3,500 - 2,400 = 1,100, right?😮
You may want to briefly scan the species cards first. Often times, more than one location will have a viable solution. In case you cannot find a sustainable ecosystem in your chosen location, it is fine to start from scratch in a different location.
At 9:36, why do you subtract 4500 - 3000? Why would it not be 3000 - 3000? I thought that the amount of calories consumed was the second number in your parentheses? And that the first number "calories provided" was the amount of calories that that fish would provide another fish if it was consumed?
If I understood your question, you're asking why we subtracted 1500 from Red Moss and Sea Lettuce (and not 3000 from any of these species). That's because both producers have the same amount of calories provided (3000), so Blue Jellyfish will eat both equally.
@@Prepmatter Thank you. During testing, we found the following working ecosystem: Great White Shark, Blue Jellyfish, Green Sea Turtle, Loggerhead Sea Turtle, Lanternfish, Red Moss, Sea Lettuce, and Shrimp.
The eating order is unclear in the video: The species with the highest “Calories Provided” eats first…. The eating order is not simply sorted by organising the animals from the highest “Calories provided” to lowest at the very start of the task. When an animal (or producer) is consumed by another animal, the remaining amount of calories left on that Animal may change the “eating order” as the reduction changes "calories provided" of the respective animal. So in this example, if you determine the eating order right at the start by looking at the "Calories provided", you would get: (1) - Great White Shark, (2) - Blue Jellyfish, (3) - Sea Urchin, (4) - Shrimp, (5) - Loggerhead Sea Turtle, and producers do not eat. However, if do the calculations and shuffle the eating order as you go, you will end up getting the following eating order: (1) - Great White Shark, (2) - Blue Jellyfish, (3) - Loggerhead Sea Turtle, (4) - Shrimp, (5) - Sea Urchin, and producer do not eat. So the eating order changes progressively in the process.... This is not clear in the video.
Good point but I think you are mistaken in the eating order. Considering the current calories provided as you go, the loggerhead sea turtle should eat last considering after it's been eaten by the shark has the least amount of calories provided (150). Or am I missing something?
@@astriddymling6917 No, you are not missing anything. After I left the comment here, I went back to my xls and noticed the eating order mistake I made in the comments. I carried on with my prep so forgot to go back and edit it. The eating order is as follows: (1) - Great White Shark, (2) - Blue Jellyfish, (3) - Shrimp, (4) - Sea Urchin, (5) - Loggerhead Sea Turtle, and producer do not eat.
For the snow depth level, I can see that the average base snow depth in November is 0, how come we didn't select that as our lowest value when calculating the difference between the highest and lowest base snow depth?
the species are typically organized across three key depth ranges. So starting with this indicator will help eliminate two-thirds of the potential species.
I have been invited to take the game with a deadline. However I received a rejection email before this deadline and not taking the assessment. How can this happen?
@@Kevin-xs1ft I have contacted them. It was a mistake, due to some technical issues faced me and fixed it. I have completed it, but unlikely I hadn't completed the redrock study to the end 😢
You can always scan the species specifications first, but there is no clear shortcut. In the unlikely case where you cannot find a sustainable ecosystem, it is ok to start from scratch in a different location.
