Quick answer
To hit a target, the final has to make up the gap left by the rest of your grade. If you have 88% going in, the final is worth 20%, and you want 90%, you need (90 − 88 × 0.8) ÷ 0.2 = 98% on the final. If the number comes out above 100, the target is out of reach; if it is negative, you have already secured it.

How it works

needed = (target − current × (100 − weight)%) ÷ weight%weight is how much the final counts toward the grade
current
your grade before the final
weight
the final's share of the grade
target
the overall grade you want

A result over 100% means the goal is not reachable with this final alone; a negative result means you have already met the target no matter how the final goes.

Frequently asked questions

What do I need on the final to get a 90?

With 88% going in and a final worth 20%, you need 98% on the final.

How is the final grade requirement calculated?

Subtract the part your current grade already contributes from the target, then divide by the final's weight.

What if I need more than 100%?

Then the target is out of reach with this final; you would need extra credit or a different goal.

What if the result is negative?

You have already locked in the target, so even a zero on the final keeps you at or above it.
