Semester Grade Calculator
Add every assignment, test, and project from your semester to see your current overall grade, instantly and accurately.
How it works
Each row is one graded component of your semester — a quiz, assignment, midterm, or project. We multiply every score by its weight, add them up, and divide by the total weight entered so far to give you an accurate running average.
Why the total weight doesn't need to hit 100%
Mid-semester, you usually haven't been graded on everything yet. The calculator normalizes against whatever weight you've entered, so your result reflects your true standing on the work completed so far — not the whole course.
Frequently asked questions
Semester grades, assignment weights, GPA, and everything else students ask us.
Enter every graded assignment, quiz, test, or project from your semester along with its score and weight. The calculator multiplies each score by its weight and combines them into a single weighted average — your current overall semester grade.
