Final Grade Calculator

Every exam season produces the same search: "what do I need on my final?" The answer is one rearranged equation away, and this calculator does the rearranging: your course grade is current × (1 − weight) + final × weight, so the score you need is (target − current × (1 − weight)) ÷ weight. Enter three numbers — current grade, the final's weight in the course, your target — and the required score appears.

The interpretation matters as much as the number, so the tool provides it honestly. Under 70% needed: comfortably achievable. 70–90%: achievable with serious preparation. Above 90%: technically possible but demands a near-perfect exam — worth knowing before you plan your study weeks around it. Above 100%: mathematically impossible, and the tool says so plainly while showing the best grade you can still reach, so you can reset the target to something real.

There's a happy case too: when your target is already secured — when even a zero on the final leaves you above it — the calculator tells you that, with the guaranteed minimum shown. Few things improve exam week like discovering a course is already locked in. The full formula and your course's weight split are displayed under every result, so the arithmetic is never a black box.
