How Long Is AP Calc BC Exam? 2025 Section Time Limits
The AP Calculus BC exam runs 3 hours and 15 minutes of total testing time, split across two sections. Section I is multiple choice and Section II is free response. Add the break and setup, and exam day stretches a bit longer.
How the Time Is Divided
Each section has two parts, and knowing the split helps you pace yourself. According to the College Board, Section I has 45 questions: Part A allows a graphing calculator (30 questions, 60 minutes), and Part B does not (15 questions, 45 minutes). Section II has 6 questions: Part A requires a graphing calculator (2 questions, 30 minutes), and Part B does not (4 questions, 60 minutes).
For example, if you can’t finish a multiple-choice question in about 2 minutes, mark it and move on. The AB subscore questions are embedded in the BC exam and follow the same timing.
| Section | Part | Time |
|---|---|---|
| Multiple Choice | A (calculator) | 60 min |
| Multiple Choice | B (no calculator) | 45 min |
| Free Response | A (calculator) | 30 min |
| Free Response | B (no calculator) | 60 min |
Why the Timing Matters
Multiple choice and free response each count for 50% of your score, per the College Board. With 45 minutes for 15 no-calculator multiple-choice questions, that’s about 3 minutes per question. Free-response questions are worth 9 points each, so pace yourself at roughly 15 minutes per question and leave a few minutes to revisit the hardest one.
A good strategy: if you’re short on time, do the easiest free-response part first, since graders award partial credit for correct setup even without a final answer. The same logic applies to multiple choice—guessing and moving on often costs less than lingering over one lengthy setup.
Key Takeaways
- Total testing time is 3 hours and 15 minutes, with a short break between sections.
- Section I is 1 hour 45 minutes; Section II is 1 hour 30 minutes.
- Calculator and no-calculator parts appear in both sections.
- Pace multiple choice at about 2–3 minutes per question.
- Free-response questions are worth 9 points each; show your setup for partial credit.
