Exam Homework Calculator

The Exam Homework Calculator combines exam and homework performance into one weighted course component. It is designed for a simple two-category grading structure and shows how each category contributes to the combined percentage.

Use it when a syllabus assigns separate weights to exams and homework, or when you want to test how a homework average offsets a stronger or weaker exam average. The calculator also solves for the homework average needed to reach a chosen combined target while holding the exam average constant.

1. Enter exam performance
Use the current or final exam-category average.

2. Enter homework performance
Use the homework-category average after any drops or extra credit.

3. Assign category weights
Enter the relative weights from the syllabus.

4. Set a combined target
Choose the desired result for these two categories.

5. Review contributions
See the weighted points supplied by exams and homework and the homework average needed for the target.

Combined grade = (Exam average × Exam weight + Homework average × Homework weight) ÷ Total weight
Homework average needed = [Target × Total weight − Exam average × Exam weight] ÷ Homework weight

All averages and the target are percentages. The two weights may sum to 100, but any positive relative weights produce the same proportional result.

What the result means

The result is the weighted percentage for the exam and homework categories entered.

Other course categories are excluded; use the result as a subtotal when the syllabus contains additional components.

Given: Exam average 78% at 70% weight, homework average 92% at 30% weight, and an 82% target.

Calculation: Exam contribution = 78 × 0.70 = 54.6 points. Homework contribution = 92 × 0.30 = 27.6 points. Combined grade = 54.6 + 27.6 = 82.2%. Homework needed = (82 − 54.6) ÷ 0.30 = 91.33%.

Result: The combined grade is 82.2%; a homework average of about 91.34% would reach an 82% target.

What if the weights do not total 100?

The calculator normalizes them by their total, so relative weights still work.

Should I include extra credit in the homework average?

Include it only as your gradebook or syllabus applies it; averages above 100 may require a separate calculation.

Can this calculate my entire course grade?

Only when exams and homework are the only graded categories. Otherwise it is a two-category subtotal.

Why is the needed homework average negative?

That means the exam contribution alone is already enough to meet the selected target; the calculator displays 0%.

How is this different from a points-based grade calculator?

This page combines category averages by weight, while a points-based calculator combines earned and possible points directly.
