Calculating Across Multiple Subjects
If you take five subjects each graded out of 100 (Total Maximum = 500):
- Mathematics: 92 / 100
- Physics: 85 / 100
- Chemistry: 78 / 100
- English: 88 / 100
- Computer Science: 95 / 100
Sum of obtained marks = 92 + 85 + 78 + 88 + 95 = 438.
Percentage = (438 ÷ 500) × 100 = 87.6%.
Handling Theory & Practical Component Splits
When subjects combine practical labs (e.g. 30 marks) and theory papers (70 marks), ensure both are summed into the overall subject total before computing aggregate percentages.
Grading Scale Conversion: Percentage to GPA / Letter Grades
Converting percentage marks into letter grades or standard GPA scales depends on your regional education board or university framework:
| Percentage Range | Letter Grade | US 4.0 GPA | UK Honours Classification | Academic Standing |
|---|---|---|---|---|
| 90% – 100% | A / A+ | 4.0 | First Class Honours (1st) | Distinction / Outstanding |
| 80% – 89% | B / B+ | 3.0 – 3.7 | Upper Second (2:1) | Very Good / High Merit |
| 70% – 79% | C / C+ | 2.0 – 2.7 | Lower Second (2:2) | Good / Standard Pass |
| 60% – 69% | D / D+ | 1.0 – 1.7 | Third Class (3rd) | Satisfactory / Pass |
| Below 60% | F | 0.0 | Fail | Unsuccessful / Retake Needed |
