AP Physics 2: Algebra-Based Exam Format & Section Breakdown
A complete walk-through of the AP Physics 2: Algebra-Based exam, drawn from the College Board AP Course and Exam Description: total timing, per-section breakdown, official unit weightings, and the FRQ types you will see on test day.
Section breakdown and timing
| Section | Items | Time | Weight |
|---|---|---|---|
| Section I — Multiple Choice | multiple-choice questions | about 90 minutes | ~50% of score |
| Section II — Free Response | free-response questions | about 90 minutes | ~50% of score |
Total exam length: 3 hours.
The AP Physics 2: Algebra-Based exam runs 3 hours end to end and is split into the following sections:
- Section I — Multiple Choice — multiple-choice questions, about 90 minutes, ~50% of score.
- Section II — Free Response — free-response questions, about 90 minutes, ~50% of score.
The College Board publishes the full Course and Exam Description (CED) for AP Physics 2: Algebra-Based on AP Central, including the official unit weightings reproduced below, sample multiple-choice items, and at least one full set of released free-response questions with scoring guidelines. ExamEdge US treats that CED as the source of truth for what is testable; every unit guide on this site corresponds to a unit in the official framework, and every FRQ walkthrough on this site mirrors the structure of a real released question.
Understanding the section breakdown is itself a score-lift technique. Many students who report "I knew the content but ran out of time" did not budget per-question time before walking in. Use the per-question time implied by the table above as a hard pacing limit during practice — for example, if Section II of AP Physics 2: Algebra-Based gives you 90 minutes for 6 free-response questions, your average is 15 minutes per FRQ, and any FRQ that you have not at least sketched in 15 minutes should be skipped to the next so that you maximize point capture across all six.
The unit weightings below indicate the percentage of multiple-choice questions drawn from each unit in a typical release. Two practical implications: first, no unit is small enough to skip — even a 5–7% unit will contribute a measurable number of multiple-choice points. Second, the highest-weight unit on the exam deserves at least one full study session per week from week 2 onward, because a 17–20% unit will materially move your final score in either direction.
For each section above, the College Board publishes targeted skills (in AP Biology these are called Science Practices; in AP US History they are Historical Reasoning Skills; in AP Chemistry they are Science Practices). The skills do not change between exam years, so a student who masters the skill list will be able to answer next year's questions even though the specific stimuli will differ.
