The cheapest way to prepare for AP Exams
You can prepare well for free with AP Classroom, College Board’s past free-response questions and Khan Academy. The cheapest paid help is a Princeton Review book at about $20 to $28 per subject; if you’re taking several APs, Fiveable’s $79 a year for every subject costs less than buying per-subject help for each.
Each provider’s price from its own pages; Princeton Review book prices from retailers. Checked October 12, 2026.

Cheapest first.
Taking several APs
Per-subject prices multiply. Three subjects cost $237 on Albert and at least $297 on UWorld’s 30-day plans, against $79 for a year of Fiveable covering all of them.
Ways to pay less
- Ask your teacher what your school already licenses; your school may already license Albert or another platform.
- Use UWorld’s 7-day free trial before paying, and its 20% discount when buying three or more College Prep products.
- Cut the exam fee too: College Board’s $37 fee reduction usually brings an exam to $53, and some states cut it further.
