Free-response is where students lose the most points and teachers spend the most time. AbiSabi scores free-response answers against the official rubric and explains exactly where points were earned and lost — in minutes, not days.
Official rubrics
Responses are evaluated point by point against the College Board scoring guidelines, so feedback reflects how the exam is actually graded — not a generic impression of the work.
Snap a photo of handwritten work
For subjects like AP Calculus, students work the problems on paper as they would on exam day, then upload a photo or scan. AbiSabi reads the handwriting and grades the booklet — no retyping required.
Point-by-point breakdown
Each response comes back with a per-criterion score and a short explanation, so students know which step cost them the point and what a full-credit answer needed.
Hours back for teachers
Automating first-pass free-response feedback frees teachers to focus on the conversations that move students, instead of grading the same rubric a hundred times.
