What if the tool says I need over 100%?

It means your target is mathematically unreachable — even a perfect score on the final can't lift the course grade that high. The tool shows the best achievable grade (what you get with a 100% final). Adjust your target downward or look for extra credit.

Can I get a lower grade on the final and still hit my target?

Yes, if your current grade already exceeds the target when weighted appropriately. The tool also shows the minimum final score that keeps you at target — useful if you want to coast or check your safety margin.

What exactly does 'final weight' mean?

The portion of your course grade the final represents. If the syllabus says 'final exam: 25% of grade', enter 25. Your current grade then represents the remaining 75% of your total. The math: final course grade = current × (1 − weight) + final × weight.
