What Do I Need on the Final to Get a 90? (Current: 85, Final Worth 20%)

Frequently asked questions
- Why is the score I need above 100%?
- A result above 100% means a perfect final still isn't enough to hit your target with the final's current weight. You would need extra credit, a lower target, or a different grading scheme.
- What does a negative or zero result mean?
- It means your current grade already guarantees the target — even a 0% on the final keeps you at or above it.
- Does this account for other remaining assignments?
- No — it assumes the final is the only graded item left. If other work remains, roll it into your current grade and adjust the weight so the final's weight is correct.
