Diagnostic

Written in the AP United States History exam's format and at its difficulty: the multiple choice for every unit you've learned, then free response if you want it. It runs like the exam: one multiple-choice section on the AP clock, 1 minute a question (55 questions in 55 minutes on the real exam), in sets that share a passage. You’ll see exactly which topics you’ve got and which to work on first. The clock pauses whenever you leave the page, and picks up where you were when you come back.
