  • a minimum 2.7 GPA in all pre-major courses
  • a minimum grade of C or better in all pre-major courses*^
  • a minimum 2.0 cumulative GPA

*Students are allowed to repeat up to 2 pre-major courses in which they received a C- or below. Please see our Academic Eligibility page for more details.

Automatic Admission to the Pre-Major for Entering Students
