Start free. College Board’s exam description for your subject tells you exactly what’s tested, and Modern States has free courses for most exams, with a voucher for the exam fee when you finish. If you want more practice questions, the apps and websites below are the ones people actually use. We checked each one’s price and what’s free in October 2026.
Start here for any CLEP exam. Each exam page lists the number of questions, the time and how much each topic counts. The sample questions show the style, but they don’t explain the answers.

For each exam, College Board lists free outside courses and websites, such as Modern States, Khan Academy and subject sites. They aren’t written for CLEP, and College Board says it can’t vouch for their accuracy, but they’re a good starting list.

The best-known free route. Finish a course with a 75% average on its quizzes and 75% on the final, and you can request a voucher that covers the CLEP exam fee for that subject. You still pay the test center fee, though Modern States says you may be able to get it reimbursed, so keep your receipt. College Board links its courses on several exam study pages.
