Math 3

Math 3, Precalculus, is a preparatory course for students in economics, engineering, or the physical or biological sciences.

Prerequisites

Before enrolling in Math 3, you must satisfy one of the following prerequisites:

MP tier 200 or higher, or
completion of Math 2 with a grade of C or better.

Who should take Math 3?

Math 3 is the recommended preparatory course for students intending to take Math 11AB or Math 19AB whose best MP tier after reassessment is 200, and who do not have an AP Calculus score or 3 or higher.

Math 3 is recommended for calculus-bound students who whose most advanced math course is advanced algebra or the equivalent. Students who have successfully completed a precalculus or trigonometry course are strongly encouraged to improve their placement through review in their ALEKS Learning Module and reassessment.
