Senior grades for computer science?

If I get a C both semester for Calculus 1, are my chances of entering UCSC CS 5% to none? What if I get a 3/4 on the AP Exam?

Your provisional admission to UCSC requires you maintain a 3.0 weighted GPA and no D’s or F’s. UCSC does not see your Senior grades until you are admitted and enrolled. Your admission to UCSC will depend upon your UC GPA from 10-11th grade, test scores, EC’s, # of AP classes and essays. So what were your qualifications upon applying?

In accepting admission at UCSC, you agree that you will:

  1. Earn a level of academic achievement in your fall and spring courses (as you listed on your UC application) consistent with your previous coursework. Earn a grade of C or higher in those courses (or equivalent for other grading systems).
