Formula used
w is the final exam weight as a decimal (30% = 0.30).
Worked example
Current grade 78%, final worth 30%
To finish with 80%: (80 − 78 × 0.7) ÷ 0.3 = 84.7% needed
To finish with 85%: 101.3% needed — not possible
Maximum achievable with 100% on the final: 84.6%
Planning your preparation
Knowing the required score early helps you set a realistic goal. If you need over 90% on a heavily weighted final, start revising weeks in advance and focus on topics that carry the most marks. If the target is out of reach, the calculator shows the maximum grade still possible so you can plan for the next term.
Tips for accurate results
- Use your weighted current grade, not a simple average of tests.
- Check whether assignments are still due before the final.
- Ask your teacher for the exact weighting scheme.
