GMAT Tip of the Week for the Week of August 20, 2012

This week’s GMAT tip* concerns choosing between answer choices D & E on GMAT data sufficiency questions. Check out this video to learn more:

GMAT Tip of the Week: One of the more useful GMAT strategies on GMAT data sufficiency questions is to know how and when to eliminate clearly wrong answer choices once you’ve made a determination about the sufficiency of one of the statements. Often, the two statements contain very different and distinct information. Sometimes, however, the statements provide you with essentially the same information, as in the example explained in the video above.

When you are given essentially the same information in both statements of a GMAT Data Sufficiency question, you should immediately eliminate answer choices A, B, and C as possible correct answers. Because the information in the statements is the same, that information will either be sufficient to answer the question, in which case the correct answer will be D (meaning that either statement is sufficient to answer the question), or it will not be sufficient to answer the question, in which case the correct answer will be E (meaning that you need more info).

Even if you’re unable to ultimately determine sufficiency or insufficiency, at the very least this GMAT strategy will enable you to improve your guessing odds on a question like this to 50-50, which puts you in a great position to get more right answers and a higher GMAT score!
