AP Chem (AP Chemistry) is a challenging AP science course that tests your mastery of chemical concepts, laboratory skills, and problem-solving abilities. The course covers college-level chemistry topics and prepares you for the AP Chemistry exam in May.
This guide covers:
- AP Chem course overview
- Exam format and timing
- Scoring breakdown
- Key topics to master
- Study tips and strategies for success
AP Chem Course Overview
AP Chemistry is designed to be equivalent to a first-year college chemistry course. It requires a strong background in algebra and scientific reasoning. The course includes both classroom instruction and laboratory work.
The main focus areas include atomic structure, bonding, chemical reactions, thermodynamics, kinetics, and equilibrium.
AP Chem Exam Format
The AP Chemistry exam is 3 hours and 15 minutes long and is divided into two sections:
- Section I – Multiple Choice (90 minutes): 60 questions, worth 50% of the score
- Section II – Free Response (105 minutes): 7 questions (3 long, 4 short), worth 50% of the score
The exam tests both your understanding of chemical principles and your ability to apply them in experimental and real-world contexts.
AP Chem Scoring Breakdown
Multiple Choice:
- 50% of total score
- No penalty for wrong answers
Free Response:
- 50% of total score
- Includes experimental design and data analysis
Scores are converted to the AP 1–5 scale:
- 5 – Extremely well qualified
- 4 – Well qualified
- 3 – Qualified
- 2 – Possibly qualified
- 1 – No recommendation
