Score breakdown for a 10-point test

How this is calculated
Divide the points earned by the points possible and multiply by 100: 4 ÷ 10 × 100 = 40%. On the common 10-point-band scale that lands in the F range — you'd have needed 9/10 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.
How do I calculate what I need on my final?
Take your target grade, subtract your current grade multiplied by the portion of the course that's already graded, then divide by the final's weight. Example: you have an 85, the final is worth 20%, and you want a 90 overall — you'd need (90 − 85×0.8) ÷ 0.2 = 110%, which means a 90 isn't reachable and your realistic ceiling is an 88.
