The Quantitative (“Quant”) section of the GMAT contains 37 multiple-choice questions, and you’ll have 75 minutes to finish this portion of the exam. Calculators are not allowed, making your task a lot harder. Scores can range from 0 to 60, but scores above 50 are very rare. Like the Verbal section, Quant is computer-adaptive, so you can’t proceed to another question until you’ve answered the current one, and you can’t go back and change your answers. Because you only have 75 minutes to answer 37 extremely difficult questions, pacing is very important. You must balance the need to spend adequate time on each problem with the need to try to answer them all. A wrong answer doesn’t penalize you any more than an unanswered question does, so it’s important to try to answer every question, even if you have to guess on some of them.
There are two kinds of GMAT Quantitative questions: Problem Solving and Data Sufficiency. Problem Solving questions will measure your abilities in arithmetic, basic algebra, and basic principles of geometry, your ability to grasp which and how much information is necessary for solving problems, and your ability to think mathematically and read graphs.
For Data Sufficiency problems you’ll be presented with a question, which will include some initial facts, followed by statement 1 and statement 2. You will then have to determine if you can answer the question based on the data in the statements. You will have five choices for each question: a) 1 is sufficient, but 2 isn’t, b) 2 is sufficient, but 1 isn’t, c) neither is sufficient alone, but both taken together are sufficient, d) each statement is sufficient by itself, and e) neither statement is sufficient alone, and are not sufficient when considered together. These questions will measure your abilities to analyze quantitative data, recognize which data is important, and recognize when you have enough data to answer a question.
