How Weighted Grade Averages Work
Not all classes are created equal. A 4-credit A matters more than a 1-credit A. Weighted averaging accounts for these differences to give you an accurate GPA.
GPA Calculation Example
Calculus (4 credits): A = 4.0 → 4 × 4.0 = 16.0
English (3 credits): B+ = 3.3 → 3 × 3.3 = 9.9
History (3 credits): A- = 3.7 → 3 × 3.7 = 11.1
Lab (1 credit): A = 4.0 → 1 × 4.0 = 4.0
Sum of products: 41.0 / 11 credits = 3.73 GPA
Class Grade Weighting
Many classes weight categories differently. Here's a typical breakdown:
Exams (40%): Average 88 → 0.40 × 88 = 35.2
Homework (25%): Average 95 → 0.25 × 95 = 23.75
Quizzes (15%): Average 82 → 0.15 × 82 = 12.3
Final Exam (20%): Score 91 → 0.20 × 91 = 18.2
Weighted average: 89.45 (B+)
GPA Scale Reference
- A = 4.0, A- = 3.7
- B+ = 3.3, B = 3.0, B- = 2.7
- C+ = 2.3, C = 2.0, C- = 1.7
- D+ = 1.3, D = 1.0, F = 0.0
💡 Strategy Tip
Improving a grade in a high-credit course has more GPA impact than a low-credit course. A B→A in a 4-credit class gains 4.0 GPA points, while the same improvement in a 1-credit class gains only 1.0.
