## TASC Math Objectives

Similar to the GED and HiSET, the TASC is a high school equivalency exam that tests your knowledge in math, science, reading, writing and social studies. The math subtest is 105-115 minutes long and includes 55 questions; questions types include multiple-choice, gridded-response, constructed-response and technology-enhanced formats. The math exam is divided into two parts, and you can use a calculator on the first part. Geometry questions make up about 23% of the test. You can use this chapter to prepare for questions that relate to recognizing the properties of shapes and the use geometric formulas.
