What are the chances of getting hard questions of combinatorics and probablity in exam? I am so confused over the hard ones. Is there a type pf quetsions that i can refer to ? Also how many questions on an average come? I refer MGMAT guide. Would that suffice?

You mean to ask...probability of tough questions in probability:).

Well, I would say this would be no different from the general format of the exam: if you are performing well in the test, then you get increasingly tougher questions.

In terms of total number of questions in P&C, if I had to choose a number, I would say: Definitely not more than 4.

Hi AlN,

In general, Permutations, Combinations and Probability questions are typically considered harder-than-average because each of those question types is a subject that most people never learned while they were in school (and those questions often require a specific formula or logic to solve). That does NOT mean that every question in those 3 categories is difficult though - and you might see some fairly 'simple' versions of those questions on Test Day. From a frequency-standpoint, none of them are all that common on Test Day either - you will likely see 1 of each; they might be difficult, but they might not. The "hard" questions that you see on Test Day could just as easily be based on other subjects, such as multi-shape Geometry, advanced Algebra, etc.

When it comes to averages, you will almost certainly see at least 1 question that refers to the standard 'average formula' and another that refers to 'average speed.'

Studies:
1) How long have you studied?
2) What study materials have you used so far besides the books that you mentioned?
3) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?

Goals:
4) What is your goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?

Thanks Rich

So my aim is to get a score of 720+ and aim for Asian and European B schools. I have started studying from Jan and have been using MGMAT books and OG. I am planning to give the exam by end of June

Hi AlN,

From your message, I assume that you have NOT taken any practice CATs/mocks yet. Since you've been studying for the last 1-2 months, then you really MUST take a FULL-LENGTH CAT sometime soon (perhaps this weekend) and at regular intervals going forward. This is the only way to truly track your progress. Make sure to take the FULL CAT (with the Essay and IR sections) and do so in a realistic fashion (take it away from your home, at the same time of day that you plan to take the Official GMAT, etc). Once you have that score result, you should post back here (or you can PM me directly) and we can discuss the results.

GMAT assassins aren't born, they're made,
Rich

The chances are quite low. I took the GMAT recently myself, and I only saw one combinatorics problem - and it was a fairly straightforward one that could be solved by writing out all of the cases. It's possible that you'll see more, but you definitely won't see very many. I'd recommend that you ignore probability/combinatorics until you're consistently scoring in the 80th percentile on Quant on practice tests. If you're already there, just take time to get comfortable with easier probability/combinatorics, but you still don't really need to worry about the super hard ones - not even if you're aiming for a 50-51.

Hi AIN,

You ask a really good question; however, you probably won’t get a definitive answer. If we all knew the exact breakdown of topics to expect on any given GMAT, the test wouldn’t be such a challenge, right? Remember, part of the difficulty of the GMAT is the fact that so few quant questions are asked (only 31), but so many concepts can be tested. Thus, to be successful on the GMAT (and especially to score 720+), you must be ready for ANY quant topic or any difficulty level that could be thrown your way on test day.

I agree that since you have been studying for a few months, you should determine your baseline score. If possible, you should take a full-length GMAC practice exam. Once you complete the exam, feel free to report back here, and I can provide some further advice. Also, you may find it helpful to read this article: How to Score a 700+ on the GMAT — A Mini Guide for Success.

Good luck!
