Final grade calculator

Plug in your current standing, target grade, and the exam weight from your syllabus. We solve for the final percentage you need.

• Let C be your current grade percent, D the desired final percent, and w the final weight as a decimal.
• Required final F satisfies D = C·(1−w) + F·w, so F = (D − C·(1−w)) ÷ w.

1. Gather C from your gradebook, D from the syllabus target, and w from the final exam line.
2. Write w as a decimal (for example, 40% → 0.40).
3. Solve F = (D − C·(1−w)) ÷ w with the calculator to avoid algebra mistakes.
4. Interpret impossible F values (above 100 or below 0) as a sign to revisit targets or weights.
5. Recompute whenever partial grades change before the final.

• Model every assignment before finals arrive.
• Study tactics when the term still has room left.
• Cross-check category math in the Grade Calculator if your current percent C still moves week to week.
