Model every scenario before finals: see exactly what you need
The ClassOS GPA Simulator lets you run what-if scenarios across all your courses. Change a letter grade and watch your projected GPA move, then build a strategy to hit your target.

Before you decide which class gets your weekend
You need a certain GPA for a scholarship, and you have been doing the arithmetic in your phone calculator, guessing at credit hours. The simulator starts from the grades ClassOS already synced, so you can move one course and watch the credit weighted projection move with it, before you decide where the weekend goes.

How it works
- 1
ClassOS loads your current grades from Canvas
The simulator starts with your real grades (no manual entry). You see your current GPA and how each course is contributing to it.
- 2
Model the scenarios
What if you got an A on the final? What if your chemistry grade drops? Change the grades and watch your projected GPA update instantly.

Get the exact score you need
The Finals Calculator tells you precisely what you need on each remaining exam to hit your GPA target. Then Scout builds the study plan.
Common questions
Is the GPA calculation accurate?
Yes. ClassOS uses standard 4.0 scale GPA calculation weighted by credit hours. It matches what your registrar uses.
Does it work with plus/minus grades?
Yes. A+, A, A−, B+, B, B−, etc. are all supported and use the standard grade point values.
Is the GPA Simulator free?
Yes. The GPA Simulator and the Finals Calculator both run on the Canvas data ClassOS already synced, so there is nothing to meter: every account gets them. Pro ($4.99/mo) raises your Scout message and AI-generation allowances, not your access to the math.
