SAT Math Practice Problems: Getting Ready for One Tough Test The SAT Test is taken by students and it assesses a student’s readiness for college. It has three sections: reading, mathematics and writing, and today we will be focusing on the math part, also known as the Quantitative Section. Within the math section of the SAT there are three sub-sections: one with 20 multiple choice questions (25 minutes), one with 8 multiple choice and 10 grid-in (write your answer in a provided box) questions (25 minutes) and finally, another section with 16 multiple choice questions (20 minutes).

Four-function, scientific and graphing calculators are allowed on the math section of the SAT, but not on the other two sections, and calculators with QWERTY keyboards are not permitted at all. The types of questions contained in the math section of the SAT are geometry, algebra, statistics, operations, probability and data analysis. The average score on the math section is 515.

Practice Problems

Below are some SAT math practice problems, and they cover most of the types of questions a student may run into while taking the test, including multiple choice and grid-in questions. The answers are in the next section. Good luck!
