Required Exam Score Calculator
What score do you need to reach your target grade? Includes a what-if table showing final grades at different exam scores.
How the Required Exam Score Calculator Works
This calculator tells you the exact score you need on a specific exam or assessment to reach your target overall grade. Unlike the Final Grade Calculator, it also shows a what-if table so you can see how different exam scores would affect your final grade.
The Formula
Required Exam Score = (Desired Grade − Current Grade × (1 − Exam Weight)) / Exam Weight
Final Grade at Score X = Current Grade × (1 − Weight) + X × Weight
Worked Example
Scenario
David has 82% in his course. The final exam is worth 40% of his grade. He wants to finish with 90% (A).
Calculation:
- Current weight: 100% − 40% = 60%
- Required = (90 − 82 × 0.60) / 0.40
- Required = (90 − 49.2) / 0.40
- Required = 40.8 / 0.40
- Required = 102%
David needs 102%, which is impossible. The what-if table shows that even 100% on the final gives him only 82 × 0.60 + 100 × 0.40 = 89.2% (a B). He might need to adjust his target to 89% or seek extra credit.
Interpreting Your Results
- Required score shown: This is the minimum exam score needed to reach your target grade.
- Grade bracket: Shows what letter grade bracket your required score falls into, giving you context.
- What-if table: See how different exam scores (50%, 70%, 90%, etc.) would affect your final grade.
- Already achieved: Your current grade already meets or exceeds your target.
- Impossible: Even a perfect score can\u2019t get you to your target. The maximum possible grade is shown.
