Understanding the AP Chemistry Exam
The AP Chemistry exam is designed to measure your understanding of chemical concepts, the ability to apply them to new situations, and your proficiency in scientific reasoning and lab skills.
The exam is split into two main sections:
Section I – Multiple Choice (50% of score)
- 60 questions in 1 hour 30 minutes
- Mixture of discrete and stimulus-based questions
- Calculator not permitted
Section II – Free Response (50% of score)
- 7 questions in 1 hour 45 minutes:
- 3 long free-response questions
- 4 short free-response questions
- Calculator permitted
How the AP Chemistry Exam is Scored
Each section contributes half of the total score:
- Multiple Choice – 50%
- Free Response – 50%
Your raw points from both sections are combined and scaled to the AP 1–5 scale:
- 5 = Extremely Well Qualified
- 4 = Well Qualified
- 3 = Qualified
