How Long Is the AP Precalc Test? Exact 2025 Timing
The AP Precalculus Exam takes 3 hours in total, split into two sections with a short break between them. Section I (multiple choice) runs 1 hour 45 minutes, and Section II (free response) also runs 1 hour 45 minutes. That’s the full official timing set by the College Board.
AP Precalculus Test Length
The exam is divided into two equally weighted halves. Section I contains multiple-choice questions across two parts: Part A allows a graphing calculator, and Part B does not. Section II contains free-response questions, also split into a calculator and a no-calculator portion.
Each section lasts 1 hour 45 minutes, so the exam itself occupies 3 hours 30 minutes of combined testing time — plus a short break after Section I. The proctor reads instructions before each section, which adds a few minutes in practice.
A quick example: if testing begins at 8:00 a.m., Section I ends around 9:45 a.m., a short break follows, and Section II finishes near 11:35 a.m. That’s the realistic window to expect on exam day.
Section Timing Breakdown
Here’s how the time is split within each section:
| Section | Part | Time | Question Type |
|---|---|---|---|
| Section I | Part A | 60 min | Multiple choice, calculator allowed |
| Section I | Part B | 45 min | Multiple choice, no calculator |
| Section II | Part A | 30 min | Free response, calculator allowed |
| Section II | Part B | 60 min | Free response, no calculator |
The pacing matters. Section I has 40 multiple-choice questions total (28 with a calculator, 12 without). Section II has 4 free-response questions — 2 requiring a calculator and 2 without.
The practical takeaway: budget your time by section, not by question, and practice under these exact limits before test day.
Key Takeaways
- The full AP Precalculus Exam lasts 3 hours, split evenly into two 1 hour 45 minute sections.
- Section I is multiple choice; Section II is free response — each has a calculator and no-calculator part.
- Expect roughly 3 hours 30 minutes of actual testing time plus a short break and instruction reading.
- Practice with a timer using this exact breakdown so your pacing feels automatic on exam day.
