<p>I will offer this, and hopefully you can take some use from it:</p>
<p>The GMAT is an adaptive test, where the answer to each question determines what question you will get next. On the GMAT, you cannot go back and review or change your answers, so time management is essential. Also, because the test is adaptive, the first questions in each section will be the most important, and here’s why. If you get the first question right, you will earn a certain number of points and your next question will be harder and worth more points. If you get it wrong, you get no points and your next question will be easier but be worth fewer points. As you move on each section, the difference in point value between questions gets smaller and smaller, because the computer has established a general range with the early questions and uses the later questions to reach a more detailed score. So if you get all of, say, the first seven questions right in a section, you’re in very good shape to get a high score, even if you have trouble at the end, certainly better than someone who misses, say, three of their first seven, even if they finish strong at the end and actually get more questions right than the first candidate. It’s the score from the difficulty that matters.</p>
<p>This also means you want to practice a lot with a good simulation, because time management gets trickier. In the standard tests like the SAT, you generally give yourself the same amount of time on each question with a buffer at the end to review your answers. With the GMAT you won’t be able to review your answers or make changes, so your buffer need is much smaller, and because the first questions in each section are much more important than those at the end, you should take more time if you need to to get them right. It’s counter-intuitive, which is why the simulations matter so much. </p>
<p>The GMAT deals with verbal and math skills the same way that the SAT does, but the GMAT will also ask analytical questions, as well as test your ability to make quick calculations using multiple data sets.</p>
<p>Going back to percentiles, the thing you want to keep in mind is that any good school will want an above-average GMAT score, so a solid percentile ranking matters. Also, every graduate school of business will require certain core courses, and many schools look at the GMAT results to decide whether you have to take prerequisite courses before formal admission to the degree program. So your percentile ranking matters.</p>
<p>And for the record, I took the GMAT in the spring of 2006, and earned a 730.</p>
