One of the biggest challenges on the GMATÂ® is the battle against the timer. But the first thing that test-takers have to realize that it is not a test where a section cannot be completed in 75 minutes. Even the seemingly time-taking problems or calculations always have a straightforward solution provided you pause to think about the best way of going about solving a problem rather than jump into it. Usually the speed-breakers are Data Sufficiency questions involving inequalities. The first reaction of test-takers is to randomly plug numbers and see how things will pan out. Since they have not taken the time to first define the problem well, plugging numbers tends to become a trial and error process in the hope of hitting upon the answer rather than a process of testing the inequality! Over the next few Quantitative posts we will look at methods to effectively tackle Data Sufficiency problems involving inequalities. One of the first methods of decreasing the solving time required on these problems is to test the converse of the …
