Frequently asked questions
- What if the score needed is over 100%?
- If the calculator shows a needed score above 100%, it means the target grade is mathematically impossible given your current grade and the exam's weight. Consider adjusting your target.
- How is the needed score calculated?
- needed = (target − current × (1 − weight)) ÷ weight. This isolates the final exam variable from the weighted average formula.
