AP Computer Science A assignments, ready to grade

Three years of free-response papers — 2023, 2024, and 2025 — where students write Java by hand: methods and control structures, class design, array and ArrayList traversal, and 2D arrays. Import an editable copy and grade the code the student actually wrote against your rubric, with every proposed score yours to accept or change.

Frequently asked questions

What language are these free-response questions in?
Java. AP Computer Science A is a Java course, and the four free-response questions ask students to write Java by hand: a method with control structures, a class, array or ArrayList logic, and a 2D array traversal.
Can it grade handwritten code that would not compile?
That is the normal case on paper, and free-response rubrics award points for correct segments rather than for a running program. GradeThis reads the code the student wrote against your criteria — signature, traversal, boundary handling, return value — and proposes points criterion by criterion for you to confirm.
Which papers are included?
The 2023, 2024, and 2025 free-response papers. Preview any of them in full — each question, its parts, and its point values — before importing.
Can I change the rubric to match how I teach?
Yes. Importing gives you an independent, editable copy in your course, so you can rewrite criteria, change point values, and add or remove questions. The Exam Library entry is never modified.
