About
Not a review course. A short stop to check one topic, fix the gaps, and get back to your practice questions.
What this is
A place to pull in, check one topic, fix what needs fixing and get back on track. The navigation is the course itself: course, unit, topic, using the College Board's own unit and topic numbers. Open any page and you can see the whole course and where you are in it.
What this is not
It is not a review course and it is not a question bank to grind through. Multiple-choice questions are a quick way to check what you recognize. On the AP exams covered here, multiple choice is half of your score; the other half is free response, where you write, calculate and explain. The research on learning is consistent that practice which makes you recall and construct an answer — past free-response questions, done properly and scored against the scoring guidelines — produces the most durable learning. That is your review. This site is the short stop around it.
Why the questions are built the way they are
Every wrong answer on this site is a documented misconception, and you see why it is wrong as soon as you answer. Two findings shape that. Unexplained multiple choice can teach you the wrong answer: students later reproduce the distractors as facts (Roediger & Marsh, 2005), and feedback removes the effect (Butler & Roediger, 2008). And multiple choice whose wrong options are plausible makes you do real retrieval work, which helps you remember related material too (Little, Bjork, Bjork & Angello, 2012). Retrieval practice of any kind beats re-reading (Adesope, Trevisan & Sundararajan, 2017); recall-based practice generally beats recognition (Kang, McDermott & Roediger, 2007; Dunlosky et al., 2013).
Who makes it
The site is run by a physics graduate (MSci, University of Bristol) and qualified teacher (PGCE, University of Oxford) with more than a decade of one-to-one science tutoring. Material is compiled from the current AP Course and Exam Descriptions and a purpose-built question bank, and reviewed topic by topic; each page states its review status at the top. The process is set out in How these pages are made.
