About the Final Grade Calculator

Enter your current grade, the grade you want and how much the final exam is worth. The calculator gives the score you need, and tells you if the target is out of reach or already secured.

Your course grade is your current grade times the weight of everything except the final, plus the final score times its weight. Solving for the final score tells you what you need.

The formula

Needed = (target − current × (1 − w)) ÷ w

w: final exam weight as a decimal

Worked example

Currently 84%, the final is worth 30%, aiming for 90%

Needed = (90 − 84 × 0.7) ÷ 0.3 = 104%
Not reachable on the exam alone
A perfect 100% on the final gives 88.8%; for 85% you'd need 87.3%
