Frequently Asked Questions
About the Assignment Grade Calculator
Most students know their scores but not their standing. The Assignment Grade Calculator bridges that gap by showing not just your current grade, but the specific contribution of each item — making it immediately clear which assignments are dragging your grade down and which ones helped the most.
The "Impact" column is key: it shows each assignment's contribution in course grade points. A homework worth 20% of your grade that you scored 40% on only contributes 8 grade points — but a final exam worth 30% that you scored 90% contributes 27 points. Understanding this distribution helps you allocate study time effectively.
Drop Lowest simulates what happens when an instructor drops the worst quiz or homework score, which is common in many courses. Toggle it to see the grade improvement, and check whether studying hard for an optional extra credit item is worth the time compared to improving the mandatory assignments.
Formula Used
Course Grade = Σ(Score/MaxScore × Weight) across all tasks
Impact = (Score/MaxScore × Weight) contribution to total

Example Calculation
Tracking grade impact across a full semester of assignments
📥 Inputs
- Problem Sets ×8 (20% total): avg 88% each
- Lab Reports ×6 (25% total): avg 79%
- Midterm 1 (15%): 84%
- Midterm 2 (15%): 71%
- Final Exam (25%): 80%
🔢 Calculation Steps
- 1Problem Sets: 0.20 × 88 = 17.6 grade points
- 2Lab Reports: 0.25 × 79 = 19.75 grade points
- 3Midterm 1: 0.15 × 84 = 12.6 grade points
- 4Midterm 2: 0.15 × 71 = 10.65 grade points
- 5Final Exam: 0.25 × 80 = 20.0 grade points
- 6Course Grade = 17.6 + 19.75 + 12.6 + 10.65 + 20.0 = 80.6%
