Worked example
Example: 94%, 88%, 91%, 79%
- 94% = A (4.0)
- 88% = B+ (3.3)
- 91% = A− (3.7)
- 79% = C+ (2.3)
- (4.0 + 3.3 + 3.7 + 2.3) ÷ 4 = 3.33
GPA 3.33 on a 4.0 scale.
Formula
97–100 A+ · 93–96 A · 90–92 A− · 87–89 B+ · 83–86 B · 80–82 B− · 77–79 C+ · 73–76 C · 70–72 C− · 67–69 D+ · 63–66 D · 60–62 D− · <60 F
Some schools use a 10-point scale without plus/minus (90+ A, 80+ B …). Results can differ slightly.
