Results explained

If work so far is worth W% at grade C, and the final is worth (100−W)%, then target T requires final score F where T = (C·W + F·(100−W)) / 100. Solving for F can produce numbers over 100 (need extra credit or a curve) or under 0 (you already cleared the target).

Quick reference: final needed

F = (T×100 − C×W) / (100 − W).

Item	Detail
W = 70, C = 88, T = 90	Need about 94.7% on the final
Already above target	Needed score can be below 0
Over 100% needed	Look for extra credit, curves, or a lower target

Syllabi differ — confirm weights with your instructor.

How the estimate is built

needed = (target×100 − current×weight_now) / (100 − weight_now).

Example scenario

88% with 70% of the course done, aiming for 90% → about 94.7% on the final.

FAQ

What if my syllabus lists letter grades only?

Convert your current average to a percent first, or ask your instructor for the numeric cutoffs they use.

Does dropping the lowest quiz change this?

Yes — recompute your current percent after drops, then rerun. This page assumes the current grade you enter is final for the “so far” weight.

Can I model multiple remaining exams?

Not directly. Collapse remaining work into one weighted bucket, or run scenarios one exam at a time.

Why is the needed score over 100?

The target is out of reach with the remaining weight alone. Ask about extra credit, curves, or revise the target.
