If you score:

Between 0 and 25: you should start with Math 099

Between 26 and 50: you should start with Math 108 or Math 125

Between 60 and 75: you should start with Math 110

Between 76 and 100: you should start with Math 111

Math 099, Introduction to College Mathematics This course introduces the basic concepts of college mathematics. The course provides a review of the basic arithmetic operations and puts them into their proper mathematical context. In addition, it introduces geometry, statistics and probability, real numbers, and algebra.

Math 108, Introduction to College Algebra The course covers the language of algebra, writing and evaluating expressions, properties of real numbers, fractions, and exponential expressions, solving linear equations and inequalities, factoring and solving problems with linear equations and inequalities, solving problems involving polynomials, linear equations and functions, and the principles and procedures of working with rational expressions.

Math 110, College Algebra This course expands on the concepts of algebra; assists the student in manipulating and solving problems using graphing equations, inequalities, and mathematical problem solving methods. Students will also solve problems using functions, graphs and transformations and they will manipulate polynomials and rational functions and solve problems using exponential and logarithmic functions. The course assumes you’ve completed Math 108 Introduction to College Algebra or the equivalent course elsewhere.

Math 111, College Trigonometry This is a college trigonometry course. This course investigates the trigonometric and circular functions and requires students to manipulate and solve problems using trigonometric identities, inverse functions, and equations; solve problems using triangles, and vectors; evaluate problems using systems of equations and matrices; and explain and solve problems using conic sections. The course assumes you’ve completed Math 110 College Algebra or the equivalent.

Math 125, Mathematics for Liberal Arts This course examines various mathematical concepts and problem solving techniques and provides mathematical functional literacy for those majoring in non-technical subject areas such as intelligence, military history, economics, and management. As a pre-requisite for MA125, students should have some algebraic skill since a significant part of the course involves algebraic problem solving techniques. Students who have not taken an algebra course for several years could benefit from taking one of the university’s algebra courses prior to taking MA 125.
