Guide

How it works

Required score = (target − current grade × (1 − exam weight)) ÷ exam weight, with the weights as fractions. Your current grade is assumed to count for the rest of the course.

Example: you have 80% going into a final worth 40% and want 85% overall. (85 − 80 × 0.6) ÷ 0.4 = 92.5%.

Reading the result

Over 100% means the target cannot be reached on this exam alone. Zero or less means you have already secured it, as long as you sit the exam. Letter-grade cut-offs (for example, 90% for an A) vary by class; check your syllabus.

Common questions

What if my class uses points, not percentages?

Convert your current grade to a percentage of the points so far, and the exam weight to a percentage of the total points.

Does this work for midterms?

Yes, if the remaining assessment is a single item. Enter its weight as the exam weight.
