Exam Score Needed Calculator
Find out the minimum exam score you need to reach your target grade based on your current grade and exam weight.
Minimum Exam Score
Exam score needed is calculated by working backward from your target grade.
Required Exam Score = (Target Grade − Current Grade × (1 − Exam Weight)) / Exam Weight
Example:
- Current grade: 85%
- Exam weight: 30% (0.30)
- Target grade: 90%
- Required:
(90 − 85 × 0.70) / 0.30 = 101.7%
Common exam weights:
- Midterm exam: 15–25%
- Final exam: 20–40%
- Quizzes: 10–20%
Tips:
- If the required score is over 100%, you cannot reach your target with the exam alone
- Factor in extra credit opportunities if available
- Check if your professor drops the lowest grade
