A curated list of the best exam prep, subject-study, and learning-tool resources for students.
This is a curation list, not a code library. Every entry links out to a tool, channel, or book maintained by someone else, not to something hosted here. IB, IGCSE, SAT, and any student anywhere: add yours by opening a PR, see CONTRIBUTING.md.
Entries note when something is free, freemium, paid, or open source (FOSS), so you know before you click. Resources within each list are ordered alphabetically. See the Quality Standards for what earns a spot.

- Real and maintained. Actively available, not abandoned or a dead link.
- Accessible. Free, freemium, or clearly worth the price; note the pricing in the entry.
- Reputable. A known tool, channel, or book, not spam or an affiliate funnel.
