Grading Guidelines. PCC uses the traditional graded system of A, B, C, D, and F. In addition Degree or certificate requirements may designate certain courses as pass/no pass only, and Continuing Education uses marks such as SC and NSC. A student may repeat a course for a higher grade under certain conditions. If a student feels they received the wrong grade, they should follow the instructions in Grade Disputes. Read the Academic Standards and Practices Handbook: Grading Guidelines for the complete grading policy and Grade Definitions.
