GMAT Quantitative Section

shape Introduction

The GMAT Quantitative Section is specifically designed to measure the ability of the exam taker to analyze data and draw conclusions using reasoning skills. The mathematics concepts required to comprehend and solve the questions in the GMAT Quantitative section is equivalent to what is generally taught in secondary school classes.

In the GMAT Quantitative section there are 31 questions to be finished in a span of 62 minutes. The questions are intended to put your math aptitude skills to test. They revolve around basic arithmetic, algebra and geometry. This segment has multiple choice questions that fall in the following two classes: Data sufficiency questions: The GMAT Quantitative Section is expected to test the ability to assess the given data methodically. A question followed by two statements and five answer choices is given. These answer choices always continue as before. So it’s a smart thought to remember them all including their request. Then utilize your logical and analytical skills combined with the quantitative knowledge to check what information is required or sufficient to discover the appropriate answer. Here it’s more about checking the data sufficiency as the name suggests rather than finding the answer. Problem solving questions: This segment is intended to test your quantitative aptitudes skills and your ability to solve a problem/issue using the different mathematical concepts. The number of problem-solving questions would be more prominent in number. Each of the above two class of questions would appear in irregular request throughout the whole segment.
