Practice Dojo is a free practice site for AP exams, built and maintained by an AP teacher.
Each course is organized by the units in its College Board Course and Exam Description (CED). Every unit has three multiple-choice sets at increasing difficulty: White belt, Regular and Black belt. Most courses also have a full exam mix weighted like the real test, and every course has free-response questions with scoring rubrics and model answers.
Every question on the site is original. Questions are written to the learning objectives in each course's CED, use the exam's formats and conventions, and stay inside the course's scope. Each answer key is checked independently, and calculations are verified by computer. Each question comes with an explanation and a step-by-step walkthrough, because the point of practice is to understand why an answer is right.
Source-based courses use real primary documents, maps and data with credits and licenses listed on each course's sources page, such as the European History exhibit sources and Human Geography sources.
The site is free to use and needs no account. It is supported by advertising. Your progress is stored only in your own browser; see the privacy policy for details.
If you think an answer key or explanation is wrong, please get in touch. Corrections are welcome.
