First, double-check that your inputs match your syllabus exactly — the current grade, the target grade, and especially the final's weight. Our tools use standard weighted-average math and are exact given the numbers you enter. If you still think there's a bug, message us with the exact values you used and what you expected, and we'll look into it.

Maybe! We're always looking to cover more scenarios. Send us a description of how your class is graded — the categories, weights, and any special rules like dropped scores or replacement policies — and we'll consider adding it.

No. Every calculation happens locally in your browser. Nothing you type is sent to us or stored anywhere. See our Privacy Policy for details.
