About
The simulator replicates the real AP CSA Free-Response testing experience entirely in the browser. A split-pane layout shows the FRQ PDF on the left and a CodeMirror Java editor on the right. Students navigate freely between all four questions, flag questions for review, and access the official AP CSA Java Quick Reference sheet via a slide-out drawer. The countdown timer turns yellow at 10 minutes remaining and red at 5 minutes, auto-submitting when time expires. After submission, a review screen summarizes time used, questions answered, and character counts, with the option to download responses as a text file or grade them via the Gemini AI backend.
