Frequently asked questions
How do I calculate the grade I need on the final?
Needed = (target − current × (1 − final weight)) ÷ final weight. With an 85 now, a 90 target and a final worth 30%: (90 − 85 × 0.7) ÷ 0.3 ≈ 101.7.
What if the result is above 100?
It means the target cannot be reached with the final alone, unless there is extra credit. Try a lower target to see what is realistic.
Does it work with a 0–10 or 0–20 scale?
Yes. Use the same scale for every value (for example, 0–10 in many Latin American schools).
