How this is calculated
Divide the points earned by the points possible and multiply by 100: 40 ÷ 80 × 100 = 50%. On the common 10-point-band scale that lands in the F range — you'd have needed 72/80 to reach the A band.
Common questions
How are letter grades calculated from percentages?
Most US schools map percentages to letters in 10-point bands: 90–100 is an A range, 80–89 a B range, 70–79 a C range, 60–69 a D range, and below 60 an F. Plus/minus splits each band roughly in thirds (e.g. 90–92 = A-, 93–96 = A, 97+ = A+). Individual schools and professors can and do vary the cutoffs.
What's a passing grade in college?
Usually a D (60%) technically passes, but 'passing' and 'counting' differ: many majors require a C or better in core courses, prerequisites often demand a C, and anything below a C can trigger a retake requirement. Financial aid typically also requires a 2.0 GPA overall. Check your program's rules, not just the university minimum.
