what types of questions will be the heart of the GMAT?

[ibiza.traffic]

I have all this material to cover for Quant (5 strategy guides) and it seems I don't have the necessary time to study all of it very well.
Which types of questions are the most likely to be tested?

For example, I have read that's it's quite unlikely that there will be more than 1 combinatorics question on the exam. At the same time I have a really tough time understanding this area. So if it's the case that there will most likely only be 1 question, then I might as well skip this section altogether and not focus too much time on it.

That said, which are the areas that I should focus on. I believe a number of word problems will be there. What else?

Could someone provide a rough breakdown of the number of questions (out of the 37) that will come from each field? For example 5 q algebra, 5 questions word problems, 5 questions divisibility, 2 q probability and combinatorics etc.

That would really help me in arranging my studying time wisely.

Thanks!

if you've taken a practice test on our website (you can sign up to take one for free!), you'll be able to see a good idea of the breakdown of various question types. yes, combinatorics doesn't seem to be tested much so you may decide to let that topic go in favor of some others that may be more valuable to you..
