What Is a Test Grade Calculator?
A test grade calculator works out your test or exam score based on questions correct, weighted sections with different point values, or the final exam score you'd need to reach a target grade in a course. It removes the manual arithmetic and rounding errors that come from calculating percentages by hand, especially when sections carry different weights.

- Enter your scores — questions correct and total, section-by-section points, or your current/desired course grades.
