EV-T17

Find the final-exam score you need.

Work out the score required on a weighted final to reach the course grade you want.

Formula and assumptions: Needed = (target − current × (1 − weight)) ÷ weight, with the weight as a decimal. A result above 100 means the target is not reachable through the final alone; confirm the weighting in the course syllabus.

What this calculator tells you.

Enter your current grade, the final-exam weight from the syllabus, and the course grade you want. The tool solves for the final-exam score that lands exactly on the target and says plainly when the target is out of reach.

WORKED EXAMPLE

An 88% average with a 40% final

INPUTCurrent 88% · final worth 40% · target 90%
RESULT(90 − 88 × 0.6) ÷ 0.4 = 93% needed on the final

Questions people ask next.

What if the needed score is above 100?

The target cannot be reached through the final alone at that weighting. Check the syllabus for extra credit, dropped scores, or category weighting that could change the calculation.

Why does the exam weight matter so much?

The weight sets how much the final can move your average. A 20% final can shift an 80% average by at most 4 points in either direction; a 50% final can shift it by 10.
