## How to work out what you need on a final exam

1. Enter your current grade, the weight of the final exam and the grade you want.
2. Read the score you need on the final, and the table for A, B, C and D.
3. Add graded items with their weights below to get a weighted average.

## Questions

### How is the score needed on the final worked out?

Needed = (target − current × (1 − weight)) ÷ weight, with each value as a fraction of 100. With a current grade of 85, a final worth 25 percent and a target of 80, you need (80 − 63.75) ÷ 0.25 = 65 percent on the final.

### What if the weights do not add up to 100?

The weighted average divides by the total weight you entered. Weights of 20, 30 and 20 add to 70, so each item counts for its share of 70, and the tool says so when the weights do not total 100.

### Why does the tool say the grade is not reachable?

The needed score is over 100 percent, so even a perfect final would not reach the target. Some schools offer extra credit, which this tool does not include.

### Are the A, B, C and D cut-offs the same everywhere?

No. Many schools use 90, 80, 70 and 60 percent for A, B, C and D, but cut-offs and rounding differ between schools, so check your syllabus.
