How this is calculated

Divide the points earned by the points possible and multiply by 100: 22 ÷ 40 × 100 = 55%. 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.

Is a 90 an A or an A-?

In plus/minus systems, 90–92 is typically an A- and 93+ is an A, which affects GPA (3.7 vs 4.0). In straight-letter systems, everything from 90 up is simply an A. This calculator shows the plus/minus convention because it's the most common — your syllabus decides which applies to you.
