The purpose of the Entry Level Mathematics is to determine whether you're prepared to undertake college-level work in mathematics. The results of the test will be used to place you in the appropriate course. The ELM is composed of 50 multiple-choice questions; 45 of the questions actually count toward your score (the five that don't are random and could be scattered anywhere on the test). You have 90 minutes to complete the test.

Remember, the ELM is a placement test. It doesn't affect your admission to college, but your college uses the scores to place you in appropriate mathematics classes. The ELM test is graded using a formula that gives you a score between 0 and 80: If you score 50 or higher, you'll be placed in regular, college-level math classes. If you score below 50, you'll need to take remedial coursework in math. (The subscores given in the three testing categories will determine your remediation coursework.)

The following list will give you an indication of the basic skills and topics you should be familiar with to pass the ELM. You may wish to use this official list of ELM Topics as a checklist when you begin your review.

*Algebra*

Approximately 35%, or 15-20 questions

- Evaluate and interpret algebraic expressions
- Simplify algebraic expressions
- Express relationships among quantities using variables
- Use properties of exponents
- Perform polynomial arithmetic (add, subtract, multiply, divide, and factor)
