Mathematically impossible at this weight

How this is calculated

Solve for the unknown final score:

final = (target − current × (1 − weight)) / weight

where weight is the final exam's share of the overall grade (e.g., 0.30 for 30%).

What if it's over 100%?

It's mathematically impossible at the current weight. Talk to your instructor about extra credit — or accept a lower target.
