# UCSD Math Enrollment Requirements

UCSD offers three entry-level pathways for students entering mathematics at UCSD

- The Math 10A/B/C series are calculus courses designed for biology and non-STEM majors. Math 3C is the precalculus course that prepares students in this pathway. Math 2 is the Introductory course that prepares students for Math 3C.
- The Math 20A/B/C series are calculus courses for STEM-majors. Math 4C is the precalculus course that prepares students in this pathway.
- Math 18 is an entry-level Linear Algebra course.

The Math Placement Exam (MPE) places students from Math 2 through Math 20A.

Check your major to see which series you should enroll in.

## Math 10 Calculus Series

This series meets minimum requirements for biology and non-STEM majors and meets the general education requirements of most of the UCSD colleges. Check with your college and major to ensure this course meets their requirements.

### Math 3C: Precalculus

Math 3C is the precalculus course for those intending to take Math 10A.
