In weighted mode, add each assignment with its grade percentage and weight percentage. In final exam mode, enter your current grade, desired grade, and exam weight.

FAQs

How do I calculate my weighted grade?

Multiply each assignment grade by its weight percentage, sum all results, then divide by the total weight. For example, if a midterm worth 30% scores 85% and a final worth 40% scores 90%, the weighted grade is (85×0.30 + 90×0.40) / (0.30 + 0.40).

What score do I need on my final exam?

Use the formula: Required Exam Score = (Desired Grade - Current Grade × (1 - Exam Weight)) / Exam Weight. For example, with a current grade of 78%, desired grade of 90%, and exam weight of 25%, you need (90 - 78×0.75) / 0.25 = 96% on the final.
