Calculation Formula
If you are calculating semester grades manually, you must multiply your category score by its decimal weight and sum all categories. Note: Your weights must equal 100% for a perfect calculation.
Semester Grade (%) = (Test Avg × Test Wt) + (Quiz Avg × Quiz Wt) + (HW Avg × HW Wt) + (Part. × Part. Wt) + (Project Avg × Project Wt) + (Final Exam × Final Wt)
Example Calculation:
- Tests: 85 × 0.30 = 25.5
- Quizzes: 90 × 0.20 = 18
- Homework: 95 × 0.15 = 14.25
- Participation: 100 × 0.10 = 10
- Projects: 88 × 0.10 = 8.8
- Final Exam: 92 × 0.15 = 13.8
Total Semester Grade: 25.5 + 18 + 14.25 + 10 + 8.8 + 13.8 = 90.35% → Letter Grade A-
