Enter scores and weights
Use percentages from the official gradebook and keep each category or activity separate.
Exact percentage arithmetic
See how every score and weight shapes your grade.
Add weighted rows or plan a final exam. GradeCalc keeps course points, normalized average, remaining weight, reachable range, and formula visible. Inputs stay on the current page; there is no account, backend calculation, saved result URL, or dependence on the computer clock.
No account, upload, history, or generated result page.
Three visible checks
Enter, calculate, verify
Inspect every contribution
GradeCalc multiplies exact decimal values and shows course points beside the normalized average.
Confirm course-specific rules
Check rounding, letter thresholds, dropped work, curves, and extra credit outside the calculator.
