DO I NEED TO KNOW TRIG, PROBABILITY & PERMUTATIONS?? 24 Apr 2005, 14:24

Someone please tell me as soon as possible.

Do I really need to brush up on probability, trig and permutations? I don't remember ever seeing such questions on the paper-and-pencil ETS exams I took several years ago.

Also, if I'm not mistaken, I don't see probability, permutations or trig in ETS's "The Official Guide for GMAT Review", 10th edition.

Someone please tell me ASAP so I can get my study routine worked out...

Thanks.

You will not need trig but you will need some basic knowledge of prob/comb/perm. As a matter of fact, there are about 4-5 perm/comb problems in the PS section of the OG.

Thanks.

By the way, in case anyone is interested in knowing, I'm presently working my way through Arco's "How To Solve Algebra Word Problems", 3rd Edition (180 pages). I think it's a great introduction to the pedagogy of setting up and solving word problems. It's probably best appreciated by people with a non-math background (like me) who want to get a start on mastering this stuff.

I'm going to read Arco's book a second time, then I'm starting Barron's "Math Word Problems The Easy Way", by David Ebner, 2002 (396 pages).

If anyone else is working on getting a grip on word problems feel free to give me a buzz.

I would not suggest you to use Barron from a personal experience shared by many others. I don't know Barron's quality with other standardized test but their GMAT material is of dubious quality.

Thanks for the heads-up.

My intention is to use Barron's only in order to learn how to set-up word problems, and for nothing else. I am learning word problems more or less for the first time, therefore an overly easy text such as Barron's is appropriate at this very early stage.

About three weeks from now I plan to dump the easy texts and graduate to study materials that are tough and tricky. I'll be asking you guys for recommended texts then.

I will not suggest you to waste your money in buying Baron's book. One of my friend bought it and he is not very happy.
