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

The calculator normalizes by dividing by the total weight, so it works correctly even if weights sum to something other than 100.

How do I know the weights for my class?

Check the course syllabus. Instructors are required to disclose grading weights at the start of the term.

This tool supports three categories. Combine smaller categories (e.g., quizzes + participation) into one entry.

Calculate a weighted final grade from assignments, midterms, and finals with different percentage weights.

Weighted Final Grade vs Midterm Score

Weighted grading assigns different importance to categories. A final exam worth 40% affects your grade more than homework worth 30%.

Weighted Grade = (Score_1 x Weight_1 + Score_2 x Weight_2 + ...) / Total Weight

Each category's contribution equals its score times its weight divided by total weight. This ensures proper proportional representation.

Homework: 88% (30% weight), Midterm: 76% (30% weight), Final: 82% (40% weight).
