How to use it
- Enter your current grade, or switch to categories and enter each category’s weight and score (leave ungraded ones empty).
- Enter the final exam’s weight from the syllabus and the course grade you want, or tap a letter grade.
- Read the score you need, and the what-if table for final scores from 50% to 100%.
The formula
Your course grade is your current grade times the share of the course that is already graded, plus your final score times the final’s share: course = current × (1 − w) + final × w. Solving for the final gives the score you need: (target − current × (1 − w)) / w. If that is above 100%, the tool shows the best grade you can still reach; if it is zero or below, you already have the target.
What we tested
On October 14, 2026 we checked the page’s own functions against hand calculations and used the page in Chromium: the default case read "You need 94% on the final.", a target of 90 was reported as out of reach with 89.5% the best possible, the category mode worked out 85.73% from four categories and the score needed for 88%, and the page fitted a 390 px phone screen with no errors.
| Check | Result |
|---|---|
| 86% now, final 25%, want 88 -> 94 | pass |
| 86% now, final 25%, want 90 -> 102 (not reachable) | pass |
| 92% now, final 20%, want 90 -> 82 | pass |
| 70% now, final 40%, want 80 -> 95 | pass |
| course grade with 100 on the final | pass |
| round trip: course(needed) = target | pass |
| categories: graded weight 75 | pass |
| categories: 6430 / 75 | pass |
