*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.
