What we build
GradeCalc Lab is a lightweight web tool for weighted course grades and “what do I need on the final?” math. It is part of a small family of free student utilities (alongside TypingTest Lab and more tools coming soon).
Privacy
All calculations run in your browser. We do not store your scores, require signup, or upload your grades to a server.
Accuracy
The weighted average uses the standard formula: Σ(score × weight) ÷ Σ(weights). Letter grades follow a common U.S. plus/minus scale — always verify against your syllabus.
Contact / feedback
