I am really struggling with Probability and Combinations. I was told that one doesnt encounter many Q in GMAT on these topics.... however in the latest CAT's i attempted... there were as many as 7-8 Q's on these topics. can someone point me to a good resource for these topics?

I have heard of a book called 'Project GMAT' by veritas. has anyone used this? is it any good?

Hi,

The probability questions on GMAT test only basic understanding of probability. So I would suggest to borrow school text books from someone and study probability from that rather than veritas.

Isn't the basic of probability from OG enough?

I'm not sure if gabriel is still kicking around here (it's been almost two years since his post above!) but I think what he meant was because GMAT probability/combinatorics is not advanced (ie, is basic) it is a good idea to study from "school" (ie, basic ) math textbooks. (and not that because GMAT is basic you should seek out advanced textbooks).

As for whether I would agree with that: I would, in part. I think it is a good idea to study from school math textbooks if a) you never studied those topics in the first place or b) you feel or know that you require a better understanding of certain content. However, I think it is also very important to practice using official GMAT questions, and if you want, other *trusted* (ie, major test prep company) questions.
