Sit a timed mock and get back more than a score: the CED units that cost you points. Drill the weakest one, take another, and watch the list get shorter. Every question carries a full worked solution and every free-response a model answer.
Every AP® exam here is built to the same standard. We ship one subject at a time so every question is worked, checked, and worth your time.
Scores on their own do not teach. Every timed attempt is scored by topic, so the result is a list of what to work on rather than a number to feel bad about.
Randomized, timed sets force active recall — the opposite of passively re-reading a prep book. Retry as often as you like.
Every question shows a full solution. Free-response prompts include a model answer and a point-by-point scoring checklist to self-check against.
Per-topic accuracy shows exactly where to spend the last week before exam day, so effort goes where it counts.
What a review book and a lecture cannot do.
The engine makes students retrieve — the single most effective way to remember under exam pressure.
Math and science answers are machine-checked for accuracy; each question explains the method and why the tempting wrong choice is wrong.
Built for acceleration-minded families, with progress you can actually see — at a fraction of the cost of a live course.
AI can solve almost any physics or calculus problem in seconds. What it cannot do is tell your student when it is wrong — and it is confidently wrong often enough to matter.
The skill that holds its value is verification: re-deriving a result, checking units and magnitude, and knowing why an answer has to be what it is. That is what worked solutions and active recall build. Not answer-finding — answer-checking.
No. Every question is independently authored by Texas CBE™ in the AP® style. We do not reproduce College Board released or secure exam questions. Official past questions come from the College Board; our practice is a companion, not a substitute.
No. We are not affiliated with, endorsed by, or sponsored by the College Board. AP® and Advanced Placement® are their registered trademarks. This is an independent, AP-style prep service.
Because an AI answer does not check itself. It will produce a clean, confident solution that is wrong on a sign, a unit, or a hidden assumption, and a student who cannot re-derive the result has no way to catch it. The AP® Exam itself is timed and taken without AI, but the more durable point is this: when producing an answer becomes free, the value moves to verifying one. That is why every question here shows the full worked method and why the tempting wrong choice is tempting — not just the correct letter.
Every subject covers the full multiple-choice exam with worked solutions, plus free-response with a complete model answer and a point-by-point scoring checklist you self-check against — we do not grade free-response. Because these are math, science, and computer-science subjects, every answer is machine-checked for accuracy.
You score it yourself. Work each free-response prompt on your own, then reveal a complete model answer and a point-by-point scoring checklist to grade against. We do not grade free-response or essays — there is no automated essay scoring — which keeps every bit of feedback accurate and instant. Free-response in every subject works this same way.
Subjects go live on a rolling basis, with more to follow. Pricing will be one flat price for months of unlimited access, with no auto-renewal — shown on each subject when it goes live.
Registration for the official AP® Exam is handled by the College Board through your school. Ask your AP coordinator or counselor; our service is practice only and does not register you for the exam.
