Which strategy is better?

by albyman32 » Thu Sep 25, 2008 7:56 am
Is it better to spend as much time as necessary (even up to 5 minutes) to solve each problem when I know I can do it (but not necessarily in two minutes), then end up having to do complete guesses on the last 5-7 questions to finish or.... if I take too long on a problem, just fill in an answer, and move on in order to get to every problem in the section.

Sometimes I just get stuck when I know how to attack a problem and I know I'll get the answer right but the computation is taking me a while (i.e. long division, screw up by making a math mistake somewhere along the way, etc.). Hope that question made sense...

Be Willing to Be Wrong

One of the most important strategy tips for the GMAT is to know finish every section at all costs. The GMAT test-writers explicitly state that "there is a severe penalty for not completing the GMAT test" (cf 11th Edition of the Official Guide, pg. 17). Thus, because the GMAT is a computer adaptive test, your score will go way down if you have to guess on the last handful of questions (see https://www.west.net/~stewart/gmat/qa_2.htm).

So, if you know you don't know how to do a problem, or if you know it will take you a while to do the problem, spend 15 or 20 seconds eliminating answers that are obviously wrong and then just take a random guess amongst the remaining choices.
