How do I calculate a weighted grade?

Multiply each grade by its weight, sum these products, then divide by the total weight. For example: Homework 85% (30%), Tests 78% (40%), Final 92% (30%): (85×0.30 + 78×0.40 + 92×0.30) = 84.5%.

What if my weights don't add up to 100%?

The calculator normalizes weights automatically. If you enter 30, 40, 20 (total 90%), it calculates proportionally. However, for accuracy, ensure your weights total 100%.

How much does my final exam affect my grade?

If your final is weighted 30%, it affects 30% of your total grade. To calculate impact: (Desired Grade - Current Weighted Grade) / Final Weight. Example: To get 90% with current 85% and final weighted 30%, you need (90 - 85×0.70) / 0.30 = 101.7% on the final.

What are typical course weight distributions?

Common distributions: Homework/Participation 20-30%, Tests/Quizzes 40-50%, Final Exam 20-30%, Projects 10-20%. Weights vary by course level and instructor.
