AMS 3, *Precalculus for the Social Sciences*, is a preparatory course for students in social science majors other than Economics, particularly Psychology.

## Prerequisites

Before enrolling in AMS 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 AMS 3?

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

AMS 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.
