Permutation and combinations, and Probability are my weak areas in Q. OGs don't cover complex problems in these areas, so was wondering if anyone here can point me to links or materials (or problems w/ solutions) where this topic is covered at a greater detail.

Appreciate your help in advance.

Thanks!!

crak.gmat,
I am right there with you. It's a tricky concept as it has more variations than other problem types.

https://beatthegmat.blocked/2005/08 ... d-790.html

Check out this page that has various links to permutaions/comb/prob and others.

Other thing I would do is get exposed to various problem types from book u may have and escpecially this forum(u can search the archives for these problem types). There are so many prob/perm/comb questions on this forum

Also there are many subject matter experts on this forum who have posted answers to a lot of these questions. Look through them and try to understand their thought process and explanations.

Thats about it!! Good luck!

here's one of my favorites from another forum:

the next edition of our word translations strategy guide is going to hit shelves in a couple of months; it will feature newly expanded and improved sections on probability and combinatorics.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
