A running log of what's changed on AP Exam Prep. Last entry: September 25, 2026
September 25, 2026
Rebuilt every one of the 42 subject pages around a tabbed layout (Overview, Study Guide, Worked Examples, Tips & Mistakes, Practice Quiz, Full Exam) instead of one long scrolling page. Added a new Frequently Asked Questions section to every subject's Overview tab, published this changelog, and added a Terms of Service page.
September 15, 2026
Deepened all 42 subject guides: added fully worked example problems (or sample response breakdowns for portfolio/essay-based subjects) for every unit, expanded Study Tips, and added a ranked "Common Mistakes" section to every subject. Corrected several subjects' exam-format tables (question counts and timing) against the current AP Central specifications.
August 24, 2026
Initial launch: study guides, practice quizzes, and timed full-exam simulations for all 42 current AP subjects, plus a study-streak progress tracker.
