How it works
See what you missed.
Every question has an explanation. Questions you miss are saved to a list, so your next practice can be just those.
Practice like it's test day.
Take a full-length exam with timed sections and a break, or a quick set of 10 questions when you are short on time.
Follow your plan.
Each day your Today page lists what to do next: a practice set, flashcards, or a unit to review. Close the tab and pick up where you left off.
Built to follow the real exam
Check-in, timed sections, and a 10-minute break between them
A built-in calculator where the real exam allows one
Mark for Review, highlights and notes, and a reference tool in the toolbar
Save and exit, then resume where you stopped
Works on a laptop or a phone
Know what to study next
Rate each unit Not yet, Shaky or Solid. Your Today page then points you to the biggest unit you have not mastered, so you spend time where the exam puts the most questions.
Unit maps for 29 AP courses, each showing every unit's share of the multiple-choice section
Your daily plan: practice sets, flashcards and the unit to review

Independent. APrep is not made, reviewed or endorsed by the College Board or ACT.
Practice feedback, not a score. APrep does not convert results to a 1–5 AP score, or to an SAT or ACT score.
You score your own free-response answers.
