Percentage score

How this works

This uses a standard 12-step scale: A+ (97-100), A (93-96), A- (90-92), B+ (87-89), B (83-86), B- (80-82), C+ (77-79), C (73-76), C- (70-72), D+ (67-69), D (63-66), D- (60-62), and F below 60. Some schools use a different scale (no plus/minus, or different breakpoints) -- check your syllabus if it matters for your actual grade.
