How to Calculate Your Required Final Exam Grade

Knowing what you need on your final exam allows you to prioritize study time strategically across your courses.

Weighted Grading Formula

Final Exam Required = (Target Grade - (Current Grade × (1 - Final Weight))) ÷ Final Weight.

Step 1: Enter your current class grade percentage.
Step 2: Enter the target letter grade or percentage you want to achieve.
Step 3: Enter the weight percentage of the final exam.
Step 4: See the exact test score required and check grade cutoff benchmarks.

Formula: Final Exam Score = (Target - (Current × (1 - Weight))) ÷ Weight
