Hello,

I have just gone through every math problem in the OG 12th edition which I understand consist of past GMAT questions.

However, I was surprised to find virtually no (or very few) questions about combinations/permutations.

Can anyone explain why is that? I am targetting a 700+ score so I believe I should expect to have several questions about counting methods.

Any input is much appreciated!

To my knowledge, the GMAT still has combination/permutation problems on the test

who knows why GMAC would release a new edition of their official review when it only has around 30% new problems included. (I think its a conspiracy to make more money)

there have been tons of permutation and combination questions asked in this forum though. Try adding this forum to an rss reader and you are going to gain instant access to thousands of questions.
