How this is calculated
Divide the points earned by the points possible and multiply by 100: 28 ÷ 50 × 100 = 56%. On the common 10-point-band scale that lands in the F range — you'd have needed 45/50 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.
Can I still pass if I fail the final?
Often, yes — it depends on your current grade and the final's weight. With an 80 going in and a final worth 20%, even a 40 on the final leaves you at 72. Run your exact numbers in the calculator; 'failing the final means failing the class' is only true when the final is very heavily weighted or your cushion is thin.
