Finals Calculator
Stop guessing what the final is worth: ClassOS reads the weights and does the math
The Finals Calculator takes your current grade, your course's real assignment-group weights from Canvas, and tells you the score you need on the final for the letter grade you want.

Weights come from Canvas, not from a guess.
Why this matters
The week the group chat starts guessing
The week before finals, every group chat has a different version of what you need on the final, and none of them know how your professor weighted the categories. ClassOS reads the real assignment group weights from Canvas and gives you the score for the letter grade you want, including the honest answer when that grade is no longer reachable.

How it works
- 1
Pick the course
Every course ClassOS synced from Canvas is listed with its current grade and how much of the term is already graded.
- 2
Pick the grade you want
Choose your target letter grade. ClassOS solves for the final-exam score that gets you there, using the weights Canvas reports for that course.
- 3
See what's reachable
If the target needs a 104, ClassOS says so instead of quietly rounding. You get the real number, and the next-best letter grade that is still in play.
Common questions
Where do the weights come from?
From Canvas. ClassOS syncs your course's assignment groups and their weights, so the math matches whatever your professor set up rather than assuming every category counts equally.
What if my professor doesn't use weighted groups?
Then ClassOS falls back to total points earned over total points possible, which is exactly how an unweighted course is graded.
Is the Finals Calculator free?
Yes. Same as the GPA Simulator. It reads data you already synced and runs no AI, so there is nothing to meter.
