As you probably know by now, with the inclusion of the Integrated Reasoning (IR) section came the exclusion of the one of the previously required essays. Before the test change, GMAT test takers built the Analytical Writing Assessment (AWA) score on the backs of two essays: Analysis of an Argument and Analysis of an Issue. These two essays would be scored independently—by one human and one computer—then those two scores would be averaged for a total AWA score on a 0-6 point scale in ½-point increments. In order to keep total testing time at 3.5 hours, test makers decided to cut the thirty-minute Analysis of an Issue essay and insert a thirty-minute Integrated Reasoning section. Now, only the GMAT Argument essay remains.
So what can you make of this decision? Are you better off with the Argument essay over the Issue essay? And, if so, is there a way we … Read full post

Mean GMAT scores are influenced by all sorts of factors and are, of course, derived from compiling scores significantly above, significantly below, and all points in between a plotted average. Plus, it is certainly worth noting the vast differences in the individual human beings that are submitting these scores. These folks undeniably come from extremely different educational histories and socio-economic statuses. Each person decides on his or her own level of preparation in order to achieve wildly different target scores relevant to wildly different admissions criteria. And the list of mitigating factors goes on and on. Nonetheless, comparing arithmetic mean GMAT scores from nation to nation tells an interesting if not complete story and raises at least a few novel questions.

When a Critical Reasoning (CR) question pops up on the screen, adept test takers know to read the actual question first. The Question is always found in the middle between the Stimulus and the Answer Choices. By reading the question first and, thus, depending solely on the type of CR question posed, the test taker knows how to most efficiently and effectively untangle the stimulus above.
There are many different types of CR questions, but most of them will fall under the category we at Kaplan like to call the Argument Family. The members of the Argument Family are Assumption, Strengthen, Weaken, Flaw, and Evaluation. The correct answer to every question … Read full post
