### Praxis Mathematics: Objectives

The Mathematics Content Knowledge exam is used to determine your readiness to be licensed as a secondary-level mathematics teacher. The exam tests your abilities and knowledge in mathematical connections, problem solving, reasoning and proof, representation, and use of technology. The Praxis Math test has 50 multiple-choice questions. About four questions, or approximately eight percent, of the exam covers trig.

The self-assessment quizzes that follow each video lesson help you check your understanding of the information you've learned as you go. Quizzes also help you get experience with the types of questions you find on the actual Praxis exam.
