How to Calculate
Needed Score = (Target Grade − (Current Grade × (1 − Exam Weight))) ÷ Exam Weight
Required Exam Score = (Target Final Grade − Current Grade × (1 − Exam Weight)) ÷ Exam Weight. All grades and weights are expressed as percentages or decimals.
* Example: Current 80% (worth 70% of grade), final worth 30%, target 85% → Need 95.8% on final
Step-by-Step Manual Calculation Guide
Step 1: Multiply your current overall course grade by (100% − Final Exam Weight %).
Step 2: Subtract that value from your target final course grade.
Step 3: Divide the result by Final Exam Weight % to determine required exam score.

Frequently Asked Questions
How do I calculate what I need on my final exam?
Multiply current grade by remaining weight, subtract from target grade, and divide by final exam weight. Example: Target 90%, Current 85% (70% weight), Final (30% weight) -> (90 - (85 × 0.70)) / 0.30 = 101.6%.
What if the required exam score comes out over 100%?
If the required score exceeds 100%, achieving your target grade is mathematically impossible without extra credit or a grade curve.
How does final exam weight affect required score?
Higher exam weights make it easier to raise your overall grade with a good exam score, but also increase risk if you perform poorly.
What if I get a 0% on my final exam?
Your final course grade will equal your current grade multiplied by (100% − Final Exam Weight %).
Does this formula work for midterm exams?
Yes, the formula applies to any upcoming weighted assignment or exam.
