After the 5-minute break, you are asked to respond the Quantitative
Section with 37 multiple-choice questions in 75 minutes. The math
section does not test any specific knowledge in mathematics. Rather, it
tests the common concepts in Arithmetic, Algebra, and Geometry. You even
do not need to refer to a math book.
The math section has two types of question: problem solving and data
proficiency.
For most test-takers, the math section won't be a problem. But to obtain
perfect score is not as easy as most students originally think. Our
advice is to practice, practice, and practice. You can purchase the GMAT Official Guide
to get basic concepts of math. There are also a lot of practice
questions, answered with complete explanations.
