AP Biology FRQ Grader
Long FRQs and short FRQs, both scored against your rubric.
The AP Biology exam has two long FRQs (Interpreting and Evaluating Experimental Results, plus Scientific Investigation) and four short FRQs covering models, conceptual analysis, data analysis, and source evaluation. Upload any AP Bio FRQ and our AI grader scores it point-by-point against the rubric in about fifteen seconds.
From prompt to feedback in four steps.

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 Biology free-response type.
- Question 1: Interpreting and Evaluating Experimental Results
- Question 2: Scientific Investigation

Use the official AP Biology scoring guidelines, your teacher’s rubric, or let the AI generate one based on the prompt’s task verbs (describe, justify, predict, etc.).
FAQ
Is the AP Biology 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 Biology free-response questions?
AP Bio rubrics are highly structured, which is exactly what AI grading is best at. 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.
Is FRQ Review affiliated with the College Board?
