Should I take Math 5, Math 15
or
Should I take Math 21?

Take a sample assessment exam.

Math 5: Contemporary Mathematics

CSU transferrable.
3 units.
Prerequisite: Math 120 (or the equivalent) with a "C" grade or better or the assessment recommendation for Math 5, 15, or 21.

A study of graphs and optimization, voting systems, the scientific calculator, compound interest, probability and simple statistics, and growth and form.

Math 15: Elementary Statistics

CSU and UC transferrable.
4 units.
Prerequisite: Math 120 (or the equivalent) with a "C" grade or better or the assessment recommendation for Math 5, 15, or 21.

An emphasis in the use of statistical methods as applied to descriptive statistics and inferential statistics. While discussing descriptive statistics, the students will learn to read, understand, and present data in a well organized way by use of frequency distribution, graphs, percentiles, measures of control tendency, measures of variability, correlation, and linear regression. While discussing inferential statistics, the students learn to make generalizations about population based upon a sample using probability and its laws, and several parametric and non-parametric tests, including t, chi-square, ANOVA, Wilcoxon Rank Sum, Kruskal-Wallis Test, Sign, and others. Computers will be used for statistical projects. Reading and writing skills at or above the ENGL 150 level are strongly recommended. A several page written term project will be assigned.

Math 21: Finite Math

CSU and UC transferrable.
3 units.
Prerequisite: Math 120 (or the equivalent) with a "C" grade or better or the assessment recommendation for Math 5, 15, or 21.

An introduction to the methods of finite mathematics with an emphasis on systems of equations, matrices, linear programming, and the use of Markov chains in decision making.

Intermediate Algebra Diagnostic Test

You will need to download the Free Acrobat Reader from Adobe to access the sample assessment examinations on this page.

The sample assessment tool entitled Intermediate Algebra Diagnostic Test is used to test whether or not you are ready to take Math 5, 15, or 21. There are 45 questions and you have 45 minutes to complete the exam. The test is self correcting and directions are provided. Once you complete the Intermediate Algebra Diagnostic Test, the following criteria are used to determine placement.

If you score 28 correct or higher, you are eligible to enroll in Math 5 or 15.
If your score is in the range 20-27, then you should see a counselor for assistance in the appropriate course placement.
If your score is in the range 16-19, and you passed an Algebra I course in high school, then you should take Math 120. or 106.
If your score is in the range 0-15, then you should retest at a lower level.
