Frequently asked questions
How is a weighted grade calculated?
Multiply each category’s score by its weight, sum them, and divide by the total weight: grade = Σ(score × weight) / Σ weight.
What grade do I need on the final exam?
required = (target − current × (1 − finalWeight)) / finalWeight, where weights are fractions. If the result is over 100%, the target isn’t reachable.
Do the weights need to add up to 100%?
For the weighted-grade mode they don’t have to — it divides by whatever the weights sum to — but using percentages that total 100 is clearest.
Are my grades stored?
No — all calculations run locally in your browser.
What is Grade Calculator?
A grade calculator computes a course grade from weighted categories, and works backwards to find the final-exam score needed to reach a target overall grade.
