Combinations vs. Probability strategy

by Eddie D. Tue Sep 02, 2008 3:53 pm

I feel confident math and i'm contemplating eliminating Combinations and instead concentrating on Probability. I figure that I rather understand an area thoroughly or not understand it at all, especially for an area (Combis) where I'm unlikely to see more than 2 questions. In teh event that I do see Combi q's I'll just guess strategically.

Could an instructor please give me some feedback on this strategy? has it work before?
Below are my last three quant scores

May (official): 42
Aug (practice): 43
Aug (practice): 42

Goal -Sept 15 (official): 47


Thanks so much you guy are awesome!

Sorry not to have responded sooner. I hope that this reply is still helpful for those in a similar situation!

You are right that combinatorics problems are relatively infrequent on the GMAT. If you've tried to figure that area out and are just not "getting it," you may be better putting your efforts elsewhere. In general, no matter what your weak point is, it's worthwhile to have a backup guessing approach. For many problems (including combinatorics) we may be able to eliminate one or two answers quickly to give ourselves a better chance. It is worthwhile knowing what your strong and weak areas are so that you know ahead of time where to invest and where to divest a few extra seconds.

Of course, if you have enough time before the exam, make sure to attack those weak areas!
