Worked Example
Marcus has an 82% in Chemistry. His final exam is worth 30% of his grade. He wants to end with a B (83%).
Step 1: Points already secured = 82 × (1 - 0.30) = 82 × 0.70 = 57.4
Step 2: Points still needed = 83 - 57.4 = 25.6
Step 3: Required final score = 25.6 ÷ 0.30 = 85.3%
Marcus needs an 85.3% on his final to get a B in Chemistry. That's achievable with solid studying.
The Formula
This calculator uses the weighted average formula:
Where Target is your desired grade, Current is your grade before the final, and Weight is the final exam's percentage of your total grade.
Tips for Final Exam Success
- Know your minimum: Calculate what you need just to pass, not just your ideal grade. This reduces stress.
- Start early: Don't wait until the night before. Use our study schedule generator to plan ahead.
- Focus on weak areas: If you bombed one unit during the semester, prioritize reviewing that material.
- Practice with old exams: Many professors reuse question formats. Ask if practice exams are available.
