How to Calculate Exam Scores
1
Calculate Percentage Score
Formula: Percentage = (Points Scored ÷ Total Points) × 100
Example: Scored 45 out of 50
- Divide points scored by total points: 45 ÷ 50 = 0.9
- Convert to percentage: 0.9 × 100 = 90%
- Interpretation: 90% is an A- on most grading scales
Pro Tips
- Always verify your institution's grading scale
- Round percentages to two decimal places for precision
- Use fractions for partial credit calculations
2
Determine Letter Grade
Compare your percentage to the grading scale:
Example: 88% Score
- Check grading scale: 88% falls in the B+ range (87-89%)
- Assign letter grade: B+
- Interpretation: Above-average performance
Common Variations
- Some schools use +/- grading (e.g., A-, B+)
- Others use whole-letter grades (e.g., A, B, C)
- Always confirm with your institution's policy

Advanced Calculations
Weighted Scores
Formula: Weighted Score = (Percentage × Weight)
Example: Midterm (30% weight) with 85% → 85 × 0.30 = 25.5 weighted points
Cumulative Grades
Formula: Total Grade = Σ (Weighted Scores)
Example: Midterm (25.5) + Final (40.0) = 65.5 total grade
Exam Score FAQs
Can I calculate my final grade with multiple exams?
Yes! Use weighted scores: Multiply each exam's percentage by its weight, then sum the results. Example: Midterm (30%) + Final (70%) = Total Grade.
What if my exam has bonus points?
Add bonus points to your score before calculating the percentage. Example: Scored 95/100 + 5 bonus = 100/100 = 100%.
