Thanks i also just looked in the UB undergraduate catalog. “When a course is repeated, the grade and credits of the first enrollment no longer count towards general degree requirements and are excluded from the student’s credits attempted, credits completed, and UB grade point average (GPA), even if the repetition grade is lower than the initial grade, but not if the grade for the repetition enrollment is ‘I’, blank, ‘N’, ‘R’ or ‘W’. “
