AP exam predictor: which units and question types to revise first
Upload released AP free-response questions with their scoring guidelines, plus your class tests and unit notes. ExamPredictor ranks the units and question types that come up most often and carry the most points, quoting your files as evidence, so you revise in the order that matters. It predicts topics and formats, never the actual May paper.
About the AP exams
AP exams are set by the College Board and sat in May. Most combine a multiple-choice section with a free-response section, and are scored from 1 to 5.
Each course has a published Course and Exam Description that lists the units and how much of the exam each is weighted. That weighting is the first thing worth checking a prediction against.
Where to find past papers
The College Board publishes past free-response questions, with scoring guidelines and sample responses, on AP Central for most courses.
Full multiple-choice sections are generally not released publicly; your teacher's practice exams and unit tests fill that gap.
How to predict your AP topics

Download the last three to five years of free-response questions and scoring guidelines for your course from AP Central.

Revise the top units first, then practise the free-response formats it flags against the scoring guidelines.
A prediction is a revision order, not a leaked paper. Use it to decide what to revise first, and still cover the rest of the syllabus.
Questions people ask
- Can it predict the exact AP free-response questions?
- No. Nobody outside the College Board can. It ranks the units and question formats most likely to appear, which tells you what to practise first.
- Which AP subjects does it work for?
- Any subject with past questions you can upload: calculus, biology, chemistry, history, economics and the rest.
- How many years of papers should I use?
- Three or more. It reads up to ten files at once, and recent years count for more.
