The Chemistry Placement Test is a 45-minute test that consists of 44 questions based on high school chemistry and beginning algebra. These include questions on solving simple algebraic equations, on the use of proportions and percentages, and on solving word problems.

The majority of the test deals with chemistry and includes topics taught in Chemistry 102: elements and their properties, chemical formulas, concentrations of solutions, gases, oxidation numbers, redox reactions and the concepts of acids and bases. Students are strongly advised to review skills and the Chemistry Study Guide Resources before taking the placement test.

The Chemistry Placement Test clears a prerequisite only for Chemistry 101A. In order to enroll in Chemistry 101A, students must complete two course prerequisites: Chemistry 102 and Math 152. For students interested in other Chemistry classes, please refer the class schedule for prerequisites specific to those classes.

Students may challenge the Chemistry 102 prerequisite by taking the Chemistry Placement Test and pass with 22 points or higher. This test is recommended only for those students who did very well in high school chemistry or who completed an introductory college chemistry course.

Students who pass the Chemistry Placement Test must still complete the Math 152 prerequisite (or place higher than Math 152 through the computerized placement) before enrolling in Chemistry 101A.
