Early game in GMAT Verbal and Quant 31 Jan 12:06
If you're considering taking the GMAT and have taken the time to look at strategy for the test, you've almost certainly heard this little nugget before: "The questions toward the beginning of a section are worth more points!" So, is it really true? Sort of.
Actually, you have to dispense with the idea of questions being “worth points” at all to make sense of how this works.
What’s happening as you answer questions is that the GMAT is honing in on the difficulty level that corresponds to your skill level. The scoring algorithm estimates what your score will be, based on your past responses and the difficulty levels of those questions. After each response you make, the estimate is updated, with the results of all previous responses taken into account. The next question that appears is one that the algorithm has selected as the "best" to confirm the machine's suspicions about your predicted result. Oh, and another thing: the aptness of the next question is determined not only by question difficulty but also by question type and skill type. In other words, you will be sure to get a blend of questions that covers all kinds of GMAT test concepts at the appropriate difficulty level.
At the start of a multiple-choice section, you are given a problem in the middle of the difficulty scale. At this early stage, the difficulty adjustments are dramatic: correct answers cause the questions to get harder quite quickly, while wrong answers quickly make things easier.
