Can a course taken on a Credit/D/F basis be used to satisfy a prerequisite for another course?
A Cr or D standing in a Credit/D/Fail course is equivalent to a passing grade in that course and so will be treated as such for prerequisite purposes. However, if a follow-up course requires a high grade in the prerequisite course (e.g. MATH 320 requires 80% in MATH 220), a Cr or D will not suffice.
