Good to know: Scope: one class graded in percentages, where the final exam (or any last test or project) is worth a set percent of the class grade and your current grade already counts everything else the way your syllabus weighs it. Not included: letter-grade cutoffs (where an A, B or C starts differs by school, so check your syllabus), curves, dropped lowest scores, rules such as “you must pass the final to pass the class”, and GPA — for GPA use the GPA & Weighted Grade Calculator. Points-based class? Use points earned so far ÷ points possible so far as your current grade, and the final’s points ÷ all points in the class as its weight. The math is the weighted-average method that university grade handouts teach: class grade = current grade × (1 − final weight) + final score × final weight, solved for the final score. Needed scores are rounded up to two decimals so they are always enough. Everything stays in this browser tab; nothing is sent or saved.

How to use it (step by step)

  1. 1Type your current grade in the class (the percent your online gradebook or teacher shows before the final).
  2. 2Type how much the final is worth from your syllabus, for example 20% or 25%, and the class grade you want, for example 80%.
  3. 3Read the score you need on the final. Optional: type a score in “What if I get…” to see the class grade it would give you, and check the 90/80/70/60 rows.

Words to know

Weighted grade
A grade where some parts count more than others. If the final is worth 25%, it moves your class grade more than a quiz worth 5%.
Final exam weight
The share of your whole class grade that the final is worth, written as a percent in your syllabus, for example “Final exam: 20%”.
Current grade
Your grade in the class right now, before the final. It already includes your homework, quizzes and tests with their weights.
Extra credit
Bonus points that let a score go above 100%. Change “Highest possible score on the final” only if your teacher offers it on the final.
