These are course-folder copies, not unique documents: Art and Design and Calculus share core documents. All downloaded files were checked for a PDF signature; the verification inventory records structural validation and SHA-256 hashes. “Updated” means different file bytes, which can include editorial or metadata changes. It does not imply every updated file changed the curriculum.

## Scope and method

Retrieved public PDFs directly linked in the main content of each AP Students course page and its linked AP Central teacher course page. This includes CEDs, corrections, course overviews, course-at-a-glance sheets/posters, and other directly linked PDF resources. It excludes login-protected resources, historical exam archive subpages, and other documents only accessible by deeper navigation. Existing files not currently linked were retained, not deleted. The existing `ap-business-with-personal-finance` folder was kept even though the website URL uses `ap-business-personal-finance`.

For each downloaded file, compared SHA-256/content bytes with the local copy. Saved previous versions of changed files under `archive/2026-09-16/` before replacement. The original `download_summary.txt` was retained as the previous inventory. Source-page HTML/text and machine-readable manifests are under `sources/`.
