How this is calculated
Divide the points earned by the points possible and multiply by 100: 16 ÷ 40 × 100 = 40%. On the common 10-point-band scale that lands in the F range — you'd have needed 36/40 to reach the A band.
Common questions
How many points is each letter grade worth on a test?
On the standard scale, each letter band spans 10 percentage points, so on a 50-point test a letter grade is about 5 points, and on a 20-point quiz it's about 2. That's why one careless mistake matters more on short assessments — a single 2-point question on a 20-point quiz is an entire letter grade.
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.
