Whoever else is watching this right before their exam...GOOD LUCK!!! YOU CAN DO IT!

am i watching this the night before my final? yes. will i be passing the exam? a hard maybe.

Watching this after failing the final is like watching the evidence unfold in court.

Your math, chemistry, and physics videos are what got me through the four years of my Biology degree. You are a hero. You deserve the Nobel prize.

When it comes to ACS exams I've noticed the actual chemistry isn't difficult rather learning to understand what the questions are asking is more difficult

37:41 summarizes my year in chem so well. "So uh we gotta use that criss-cross thing."

Imagine, this 2-hour lecture covers a whole semester. Big salute to this channel.

Damn my test is in an hour should have watched this earlier.

Whyyyy does it look so easy when he does it but when I get my exam I freeze up and don't know how to do it?

Ayo wheres my fall 2020 gang!?

Things you should know about not mentioned in the video: Know that transition metals require a number for instance CuSO4 would be copper 2 sulfate. Make sure you know what a pure compound is and a pure substance. Also make sure to know what dipoles are and if you have say 10g of C2H4 make sure you can figure out how many moles or grams you have of say carbon or hydrogen. Don't forget about sig figs and how to name acids. ate - ick, ite - ous. Make sure to remember how to identify aqueous solutions and solid solutions. There's videos to remember such as NAG SAG. There's also acronyms to remember strong acids and know that all strong bases have OH in their formula.

Omg I got 97 on ACS after watching this review 4 times… God bless everyone who is here with your dedicated willingness to dominate this exam..! :)

Who’s prepping for their 2021 AP Chem exam!?

I got a 94.5 on am exam because of you and my grade has been saved and i am trembling thank you so much

AP exam is tomorrow.... hope to get a 4 or 5. Good luck everyone

You are the type of people that need more viewers and subscribers, not other silly videos here on RU-vid. Thanks for helping those who are struggling, you have a kind heart.

Thank you so much! This should seriously help with my final tomorrow!!! I don't know if you are employed as a teacher, but you should be. You explain things really well--that is a quality that most teachers don't really have. They all just spit out info and tell their students to study. They work out practice problems without explaining them, it is pretty rough out there. Keep up the good work dude!

Current Time: 2:13 a.m. Exam Time: 7:30 a.m. Now this is Epic. Good luck to all those on the Chem struggle bus out there.

this covers everything for college gen chem 1, correct? I like the condensed video. By far the best chem videos produced on youtube. Keep up the great work man.

dear organic chemistry tutor, thank you so much. after watching your videos, I scored a 5 on my AP chemistry exam and finished the class with a 100! your videos are carried out very smoothly and have given me a great understanding on many topics. thanks for renewing my passion for chemistry!!! i hope to donate to you in the future :)

good luck everyone, that time has come

For all of us taking it in 2019 and then probably taking Chem 2 next semester. I wish y’all good luck Forgot to come back and tell how I did... Passed that test because of this last minute review

The night before chem final, I'm going to need this to save my arse.

For those wondering at 8, why he simply added 1 and 2 to them. It's because the concentration we are looking for is actually the concentration of H+ ions in the solution, but since there are two moles of H in the molecule we have to add that 2, on the other side since it's a base we have the OH- concentration, however since there is only on mole of OH, the coefficient in front of the m1v1 is well 1. Hope it makes sense, and that I am not mistaken hahaha.

I have my exam tomorrow morning!! I haven’t attended classes all semester wish me luck yall im hoping for a 60!!

imagine watching this video the day before your ap chem exam. haha. cant relate.

Him: rounds to the nearest whole # Sig figs: *triggered*

You have literally gotten me through my first semester of chemistry!!! Life saver!! And every teacher should put you as a resource in their syllabus!

You’ve helped me pass so many classes. I expect chemistry to be no different. Thank you for making all these.

thank you so much for putting in the time and dedication to make these amazing videos!!! my gen chem final is in a few days and your videos being there throughout the semester has helped me understand and enjoy chemistry more

I never knew that Mark Wahlberg taught chemistry. Very good video though, helped a lot.

im taking my chem final tomorrow and i currently have a 42% in the class. Ya'll wish me luck. and hopefully ill remember this so i cancome back and update yall

you have literally taught me my entire chm class in two hours. you are a genius and in two hours I have my final wish me luck!!

thank you OCT for single handedly making a whole education empire that teaches us everything! You have provided more meaningful lessons than 10,000 schools ever could.

Loved the format of just working through problems. Helped to be able to take a stab at it before watching how you solve. Your tone, speed, etc are perfect. Some videos go too fast and others too slow.

I have final chemistry exam after tomorrow, watching this helps me alot! Thanks million times to you :)

You the goat. I have never in my life commented on a youtube video before but this video (and all your others) have saved my life. Thank you!!!!

i will pass my finals i will pass my finals i will pass my finals i will pass my finals

Thank you so much for this!!! My teacher is so confusing and I have no idea what I've been doing this semester. I can't thank you enough for your videos and explanations.

you're my life saver. I have my final on Friday and I'm feeling much more confident just after the first 3 minutes of this video. Thank you Thank you so much!!!!

Man I can even express how happy I am to have found your channel... You are saving lives out here.... Thank you so much for this video

GOLD! dude thank you so much. I watched a ton of your videos all semester and was so excited to see you have this! I need to ace my final. Thank you thank you thank you sir

i would comment in every video you have that you are appreciated for these videos! You are amazing at teaching, really gifted. Many professors employed in universities today can't compare to you, because of your deep understanding of how learning really works. Your efforts save countless students all over the globe. You are appreciated! God bless will you indeed, He'll be the one to return the favor to you. Thanks!

Got a perfect score on my chem final exam! Totally recommend.

I can not thank you enough !!!!!!! you are a lifesaver. Thanks for the good work you are doing, you have no idea how this helped me with my finals. Thank you

WORDS CANNOT EXPRESS HOW GRATEFUL I AM FOR YOU. I WATCHED BOTH VIDEOS FOR MY FINAL AND PASSED. THANK YOU SOOOOO MUCH. I WILL CONTINUE USING YOUR CHANNEL AS A RESOURCE. Again, thank you. 🙏🏾💕

Everybody gangster till he starts punching numbers in that calculator.

I've taken chemistry a million times and never had I ever understood quantum numbers like i did just now. THANK YOU SO MUCH... I will probably forget again over the summer but, for now, it saved my life!

You've been a huge help throughout my engineering schooling. Just wanted to say thanks. Im going to send you some donations because you've really earned it.

if i had just watched this whole video at the beginning of the year i would have aced all of my chem tests. he explains everything so well. all these concepts that once made no sense now seem so simple. I'm ready to destroy this final on Wednesday!!!

number 9 at 42:23 I realized that by using PV=nRT, you can still solve the equation by first finding n. On top of that, PV=nRT is actually provided on the formula sheet.

I hope to God that you are an instructor somewhere and some lucky students are blessed to have you as their instructor. Unbelievable mastery of the subject!

I’m so happy to find this video and your channel. You’re so helpful. Thanks and keep it up!

Leaving in an hour to go to my ACS final, was a really great review and retaught me everything way better than the two review sessions i went to. Thank you!

The setting of 2x is a life saver

Looking at this an hour before my AP exam, thank you for this blessing kind sir.

I'm taking the ACS final today and this is helping me immensely. Fingers crossed I do well, thank you for your service!!

This is the best tutorial ever, please keep making videos and helping us pass all exams. You are a genius when it comes to explaining the material. Thank you .

This is so awesome! Thanks for uploading, it's a really helpful review!

My final is tomorrow and I am so glad I found this video !!!! Helped so much!!!! I feel so confident about this exam already !!!

The best video for review! Both concise and precise! Thank you so much. I really appreciate your help😊

Thank you so much man. You're a lifesaver, this single video helped me actually retain more information than a whole semester in General Chem.

taking my first ever college exam (it’s chemistry) in less than 30 mins, i think (and hope) i’ll do well !!

I am beyond screwed for tomorrow

Thank you for your video. I'm taking Chem 2 this semester and forgot everything from Chem 1 that I took 6 years ago. This has been extremely helpful!

This literally saved my final. Thank you so much for all your videos and hard work!!!

I’m not even taking chemistry why am i watching this

19:25 was all it took for me to finally get it. The whole point of the dimensional analysis was to get to to match up to the Molarity formula which is why it works. That’s something that an entire semester of gen chem lectures couldn’t get through to me.

Thank u very much. I cannot thank u enough. It is nice that u repeat some info again and again whenever needed even though u already explained them in other videos.

this guide saved my ass for my ACS final. on to gen. chem 2, see y'all next semester!

This video definitely helps. I got a high B on this exam last year thanks to his video and mind you I struggling on every test before then. I'm now using his other video to study for my chem 2 final, so good luck everyone

You are an amazing person, I appreciate the work you put into this and explaining everything. Very, very helpful and I hope you consider a career in teaching because you're good at it

At this point I owe you my firstborn

This video really helped solidify my knowledge for Chemistry. Ended up doing well on the ACS exam. Thanks so much!

This was amazing dude! Thank you for uploading this!

Becca Mardis Your videos are actual gifts from God. I am so glad that I found your channel. You post content on a wide variety of topics, and every video is so high quality and helpful. Keep it up!

I live for these videos. I've watched them in the shower before school, fallen asleep to them, and now im actually completely awake and invested in them. God bless this man and his clear way of explaining and easy-to-listen-to voice fr

YOU'RE so amazing!!! When I saw your video I was literally going to cry from happiness. My professor isn't even helpful. Thanks for your help!!!! You are really are helpful and such a life saver

Just starting to study for my Ap exam in 4 days, will come back in few months. Thank you!

Here we go, gots my exam in the morning!! Wish me luck, first final and been watching these vids like crazy :)

You have saved me. Thank you. I've watched ton of your videos now. I feel like I'm improving

You saved my life for my chemistry and calculus exams, THANK YOU SO MUCH!

Boutta take my final and I’m watching this literally right before it as a refresher. Good luck for anyone else trying that!

As an engineering student, ive always prefered the later 3 parts of STEM, and had a weak point in science. Being put in a Chem181 course really shook me up. Yet, with your videos such as this one, its been significantly easier to learn what I need to. Plus in HS with calc 1 and 2, you've been a lifesaver.

omg, this saved me. i have a chem final in the morning!!

thank you so much for this! i’m looking to take AP chem and organic next year and if accepted i’ll use your videos for study over the summer, that way i won’t feel bombarded. God bless

i should’ve watched this at the beginning of the semester

AP test tomorrow. Been reviewing for a month now, wish me luck lads Edit*** Too easy

Omg I love this dude. my final is an hour from now this is exactly what I needed to go over what I know! T^T I feel so much better now going into this thing. Wish me luck yall!

All I gotta say is WOW. You deserve some respect. THANK YOU FOR ALL YOU DO.

Dear God bless you. I am on the verge of tears right this moment. Giving this away for free

not me watching this video 2 days before my AP exam at 6am

I love this channel so much! May God bless you with eternal happiness!

I literally love you so much, you helped me pass Calc and now Chem. Man is a Godsend frfr.
