# Prerequisite Criteria for Math Placement

### Entry-level Math Placement

All students must meet one of the following prerequisites before they may enroll in Math 20A, 10A, 4C, 3C, or 2 at UC San Diego:

- SAT Mathematics Level 2 Subject Test score 650 or higher for Math 20A or Math 18
- SAT Mathematics Level 2 Subject Test score 600 or better for Math 10A or Math 4C
- AP Calculus AB Exam score 3 for Math 20A or Math 18
- AP Calculus AB (or BC for 2020) Exam score 2 for Math 10A or Math 4C
- Qualifying placement on the UCSD Mathematics Placement Exam (MPE)

After taking the Math Placement Exam (MPE), UC San Diego may also consider the following requirements for enrollment:

- SAT I* Math Exam score 600 or higher for Math 3C
- ACT* Math Exam score of 22 or higher for Math 3C
- ACT* Math Exam score of 25 or higher for Math 4C

*Enrollment to a class using the SAT I or the ACT as a prerequisite is not automatic. If you decide to take a math course using the SAT or ACT Math as your qualifying prerequisite, then you will need to request a preauthorization using the **Enrollment Authorization System (EASy) at: **https://academicaffairs.ucsd.edu/Modules/Students/PreAuth/. Our office strongly recommends for students to take the MPE to see if they qualify for a calculus course.
