The second part of the GMAT exam is the Quantitative Section, which is a multiple choice Math section. You will have 75 minutes to complete 37 questions.
Question Type 1: Problem Solving
Problem Solving is a question type which is often used on standardized tests such as the GMAT. You are given a question plus five possible answer choices, and you must choose which answer is correct.
Some questions will contain diagrams which you must examine. In some cases these will be drawn to scale—meaning you can estimate measurements and size relationships just by looking at them. In other cases they won't be drawn to scale. The question will tell you clearly which is the case.
Question Type 2: Data Sufficiency
Data Sufficiency problems are a question type unique to the GMAT and many people find these the most difficult kind of question on the exam.
Each data sufficiency problem consists of a question plus two statements of data. You will not be asked to provide the answer to the question. Instead you must determine whether the two statements provide sufficient data to allow you to answer the question.
You will be given directions within the test on how to answer Data Sufficiency questions - it is extremely important that you read and understand these!
Anxious about GMAT Math?
Many people are worried about the GMAT Quantitative Section, especially if they haven’t studied math for a long time. However you should not be intimidated by this section of the test, and help is available to assist you in increasing your score. The math content required is not especially difficult - it includes arithmetic, algebra, and geometry, all at high school level. There is no trigonometry or calculus on the GMAT. However, you are not allowed to use a calculator on the test - so it is important to practice your mental arithmetic!
The key to the Quantitative section is learning the question types, which are likely to be different to ones you may have seen before on other tests.
