Frequently Asked Questions
Can I use Unit Practice without logging in? Why do you recommend logging in?
Yes, you can practice without logging in, but your results are stored only in your browser's local cache. If you clear your cache, update your browser, or switch devices, or anything else affects the local cache, your saved results may be lost. To keep your progress safe, we recommend logging in before you practice. Once logged in, your results are saved permanently, and you get the full experience, including the mistake log, past score reports, and every new feature we add.
Where do the Unit Practice questions come from?
Every question comes from the College Board's official AP Progress Checks, a rare, authoritative source of unit-level practice. Each unit includes both MCQ (multiple-choice) and FRQ (free-response) items, so your practice matches the AP exam standard exactly.
How do I review my practice history and mistakes?
The system records every session in detail, including time spent, accuracy, and your answers alongside the scoring. Once logged in, you can view past practice reports in your dashboard anytime, and every mistake is added to your mistake log automatically for focused review.
How should I combine Unit Practice with AP practice tests?
Unit Practice helps you consolidate each unit and work through its hardest points, ideal for targeted study. AP practice tests simulate the real exam so you can check your overall readiness and pacing. We suggest building a solid foundation with Unit Practice first, then taking full practice tests to rehearse and find remaining gaps: unit mastery, then full simulation, then targeted reinforcement.
Will the questions and explanations be updated?
The questions come from the College Board's official Progress Checks, which are fairly stable. We track College Board updates and revise unit settings, explanations, and features as needed. Every update is announced on the site and through our WeChat official account.
Does Unit Practice cost anything?
No. Every core learning feature, including Unit Practice and AP practice tests, is free. We're committed to giving every AP student professional, systematic prep with no barriers.
