Hii Bunuel.
Will this lecture be available on GMATCLUB as a youtube link?
I think I won't be able to attend it.

Good video very well explained... I think either this video or the veritas prep's critical reasoning video will win the best tutor contest.

Best questions & answers from comments

One question from the peanut gallery - what is the best ROI in terms of investing time into concepts if you are at Q45 level? What hard questions are most likely to show up/appear on the GMAT and What concepts are a must as opposed to perhaps something one could take it easier on?
Becky Robinson wrote:
For the best ROI make sure you are well grounded in the basics. At the harder level you will also want to be well versed in probability, permutations and factoring.


Trang Phan wrote:
I find that with long factorization, errors can abound. Is there a quicker way to solve that particular DS problem in the video without factorization?
Becky Robinson wrote:
There are always multiple ways to do problems but the GMAT focuses on factoring errors many times so becoming good and consistent at factoring is your best bet to getting the most questions correct.


Trang Phan wrote:
what do you recommend for someone who only has two weeks to retake an exam?
Becky Robinson wrote:
For two weeks to take the exam in the math section, I recommend you go through the list of tested topics and make sure you know how to identify questions of that type and develop a consistent approach to each type. HIring a private tutor will make this process more efficient but, especially with just two weeks make sure the tutor focuses on whole concepts instead of individual problesm.

In addition, hard math questions tend to combine multiple concepts so it is difficult to name a topic that will be "hard" which is why it is so important to know the basics of all the topics and therefore will be able to combine them when necessary.

Hi

The statistical difference problem at 23:00 seems to have the wrong answer.

Expressed in terms of J, the increase should be:

(original - difference / original ) ( 100)

The only reason answer D works out is because original = 100 - J with the plugged in numbers provided by the Princeton Review explainer.

More generally, a formula for the answer needs to rely upon a reference point expressed without J.
