Active, randomized practice with fully worked solutions and free-response model answers — built one subject at a time so every question meets the same quality bar. Made for acceleration-minded families: study by active recall, not by re-reading a review book.
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.
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.
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.
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.
