What's on every AP course page

Click into any AP course on this site and you will find the same five-page structure on every one, mirroring the official College Board AP Course and Exam Description: an exam format page with section timing and unit weightings; a scoring rubric page that explains how the multiple-choice and free-response raw scores combine into the 1–5 AP score; a tips-for-a-5 checklist of ten practical, rubric-aware moves; an FRQ walkthroughs index linking out to six annotated free-response examples per course; and a recommended resources page listing the official CED, Khan Academy, OpenStax, and our own planning tools. On top of those five pages, every course gets a dedicated unit guide for every unit in its framework — twelve guides per course on average — each with notes, key ideas, and four practice questions with explanations.

The whole structure exists so that a student preparing for any AP exam can land on the course page within two clicks of the homepage and start working immediately, without having to figure out where the exam format is hiding or whether a particular FRQ type has been covered. The site is intentionally repetitive across courses for exactly this reason — once you have used the structure on one AP course, you know it on all 38.
