FAQ
Is the AP Calculus AB FRQ grader free?
Yes. Basic is free forever and ad-supported — grade as many FRQs as you want without an account. Plus is $3.99/month and removes ads, speeds up grading, and saves unlimited history.
How accurate is the AI on AP Calculus AB free-response questions?
Calc rubrics are very structured — setup, answer, units — which is where AI grading shines. Rev (the AI grader) follows the rubric you provide point-by-point and explains where each point landed. It is not the College Board, but students consistently report scores within 1 point of teacher grades.
Can I use my own rubric?
Yes — paste in your teacher’s rubric, the official scoring guidelines, or anything else. Or skip it and the AI will generate a defensible rubric from the prompt itself.
Do I need to type my response?
No. Take a photo of your handwritten response and upload it. Rev reads handwriting and grades against the rubric. Typed responses also work.
