The Final Exam Formula

The exam grade calculator uses this formula:

Needed on Final = (Desired Grade × 100 - Current Grade × (100 - Final Weight)) ÷ Final Weight

Example Calculation

Calculation:

Needed = (85 × 100 - 82 × 70) ÷ 30
Needed = (8,500 - 5,740) ÷ 30
Needed = 2,760 ÷ 30 = 92%

Result: You need 92% on your final exam to reach 85% overall.
