Grade Calculator: What Score Do You Need on Your Final Exam?
The Reverse-Grade Formula
You know your assignment scores and the final exam’s weight. The question: what score do you need on the final to get an A? This reverse calculation prevents last-minute panic and helps you allocate study time across subjects strategically.
Worked Example
- Internal assessment (40% weight): scored 32/40 = 80%
- Target final grade: 75% (A grade)
- Final exam weight: 60%
- Required final score: (75 – 0.4 × 80) / 0.6 = (75 – 32) / 0.6 = 71.7%
You need just 72% on the final to secure an A. If your internal score were 70% instead of 80%, you’d need 78.3% on the final — showing how strong internals lower the final exam pressure.
Multi-Component Grading
| Component | Weight | Your Score | Weighted Score |
|---|---|---|---|
| Assignments | 20% | 85% | 17.0 |
| Mid-term | 30% | 72% | 21.6 |
| Final | 50% | ? | ? |
| Target | 100% | 75.0 |
Needed final score: (75 – 17.0 – 21.6) / 0.5 = 72.8%. Use the grade calculator to compute this for all your subjects instantly.
