This is the first time I ever commented on a video. Your videos are very insightful, I have got profound learning from them. They are not just helpful in acing GMAT but also in several other real life situations which eventually helps us to become better professionally, personally and spiritually any which way. I 100% resonate with you about the mantra chanting, it was something I used to wonder. Why am I not getting any better even though I am reciting the mantra daily. The thing is as you said we have to be emotionally connected with it rather than being mechanical. Thats the missing link. Thanks a lot.
Hi Meenakshi, The rule is that every prime number follows one of the two forms: 6n+1 or 6n-1. It doesn't mean the other way around. As you have mentioned, there are a lot of numbers of the forms 6n+1 and 6n-1 which are not prime. 1. Prime numbers don't follow any pattern. So, there is no way to be sure which value of N will definitely give a prime number. 2. If a number is not of the forms 6n+1 and 6n-1, the number cannot be a prime number. This understanding can be used in some questions involving logic around prime numbers.
We can think in terms of 5n or 7n too. For example: all prime numbers are of the form 5n-2, 5n-1, 5n+1, or 5n+2. All prime numbers are of the form: 7n-3, 7n-2, 7n-1, 7n+1, 7n+2, or 7n+3. As you can see that there are a lot of expressions in terms of 5 or 7, whereas in terms of 6, there are only 2 expressions (6n-1 or 6n+1). This is the reason we commonly think in terms of 6n.
Thank you so much sir for an amazing session. for question 5 and 6, i wasn't able to actually determine as to in which it's given and lead to correct an answer by process of elimination. Is it a good way to carry with? Also any possibility of such session for Cr and how can we register for same. Thanks!
Sir could attempt the question correctly in 2.5 minutes. A lot of credit goes to the process that you have taught and that took me months to internalise. Absolutely enjoyed solving the question !!
Thanks for posting this CJ, this is extremely helpful. Was struggling a bit with CR, but this 6 hour session gives me an insight on how to think while tackling S&W questions. Is there any resource available on boldface, assumption type questions?
So I tried this passage without watching the detailed explanation in the video and I was having a hard time in answering some of the questions. Then I tried the questions again to see if the detailed explanation/comprehension actually worked. And I was able to solve all the questions with such ease within 20 seconds and this really shows the power of comprehension that you talk about. Thanks
@@GMATwithCJ yes, I watched this video for Mindset and process section. I have been following your approach of understanding individual sentence and then relationship between the two. Watched it for maintaining my RC mindset for the test.
Hey Chiranjeev, 1 hour into this webinar and I already love it. I gained a lot of clarity from this particular session. Thank you! Glad I found you before my exam haha.
So all primes greater than 3 are of the form 6n + 1 or 6n - 1. What about all primes greater than 5? Greater than 7? Do these subsets of the prime numbers each have their own patterns?
All primes greater than 3, including primes greater than 5 or 7, follow the form 6n+1 or 6n-1. Can the primes greater than 5 or 7 be also expressed in some other patterns? Perhaps, yes. I am not aware, though.
I loved this video. I didn't realize that we could go this deep in CR questions. I'm trying to incorporate this kind of thinking in my practise sessions now. Any other video of a similar kind available on your channel?
Hi CJ, Thanks for the explaination! Could you please how the solution would change if there were 5% who did not experience anything (total-union) Can it be assumed that 100% here is the number of people who experienced one or both or all 3 (union) which does not include people who experienced none
If 5% did not experience anything, then ((40+30+75) - 95) constitutes double counting, i.e., 50. 35 is accounted for by people who experienced two effects. Thus, the remaining 15% is accounted for by people who experienced three effects. Thus, 7.5% people experienced three effects. Thus, (95 - (35 + 7.5)) = 52.5% people experienced one effect.
Thank you for the session. Sir I am facing a lot, a lot of Issues with 1) Boldface and 2) Inference questions, if any video/session on that would be great help.🙏
Great session. Very simple and logical way to solve CR ques to improve accuracy. I'm going to practice using the learnings from this session. Thank you.
Great Question & a top video as ever CJ ji. It took me about 9 mins to get this question. To say that I took so long is only because of the dense text and unique argument structure ignores the fact that I actually got intimidated by the opening sentence. Once I comprehended the opening sentence, the rest of the passage was a bit easier to follow. While I would say my comprehension of this passage was ~80%, I still got the answer right. Meaning there's still 20% scope for improvement :-) Just in case you didn't notice, this was my feeble attempt at imitating the passage's argument construction rofl
