### Objectives of the Praxis I Math: Functions Course

The pre-professional skills test is intended to get an idea of the mathematical ideas and skills that a college-educated adult might need in addition to measuring their ability to solve problems. Other geometry and measurement topics on the Praxis include geometric properties, systems of measurement and the xy-coordinate plane.

Once you've completed this chapter, you'll be better prepared for the geometry and measurement section of the exam, which composes about 22.5% of the full exam. Usually there are ten multiple choice questions on the Praxis I related to geometry and measurement. You'll be allowed 75 minutes to complete the test.

The self-assessment quizzes are designed to measure how well you can use the testing methods you've learned and to give you a glimpse of how questions are designed on the actual test.
