Combinatorics/Probabilities Assistance

Post Thu May 24, 2007 12:54 pm
Does anyone have suggestions for improvement in the aforementioned topic area. I am having issues with these types of questions. I have read through the resource material on the wiki, and it all seems to make sens but then when I get to themore challenging material on my practice tests, I feel like I am spinning my wheels not knowing where to begin. Should I jsut keep doing more and more practice problems? Please help

These also tend to be the kind of question on which you can blow 8 minutes without even realizing it. Give yourself one shot at a combinatorics / probability question. If it doesn't work, make an educated guess and move on. DO NOT get sucked into wasting tons of time.

I wouldn't stress this topic too much--for the most part, combinatorics and probabilities are rarely tested on the GMAT. At most, you'll see 1-2 questions, but perhaps none at all.

My advice is to understand the concepts but don't search too hard for practice problems. If you're feeling a bit paranoid (like I did) and want to have full mastery of the subjects, think about subscribing to http://www.deltacourse.com

Good luck!
