How this is calculated

Divide the points earned by the points possible and multiply by 100: 22 ÷ 30 × 100 = 73.33%. On the common 10-point-band scale that lands in the C range — you'd have needed 27/30 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.
