AP Physics C FRQ Grader
Calculus-based mechanics and E&M, graded against the rubric.
AP Physics C is two calculus-based exams: Mechanics and Electricity & Magnetism. Upload any Physics C FRQ — with derivatives, integrals, vector calculus, and all — and the AI scores it point-by-point against the rubric in about fifteen seconds.
From prompt to feedback in four steps.
- 1
Paste the prompt — any free-response question from a teacher, prep book, or practice set.
- 2
Choose a rubric — bring your own or let the AI auto-generate one from the prompt.
- 3
Upload your response — a photo of handwritten work or typed text both work.
- 4
Get scored in ~15 seconds — point-by-point feedback you can actually learn from.
Every Physics C free-response type.
- Mechanics FRQ involving integration
- E&M FRQ involving Gauss’s law or Ampère’s law
- Free-body or circuit analysis problem
Use the official AP Physics C scoring guidelines or your teacher’s rubric. The AI follows derivations and gives partial credit when an early step is wrong but later work is consistent.
FAQ
Is the AP Physics C 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 Physics C free-response questions?
Physics C rubrics value mathematical setup heavily — the AI looks at every step. 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.
