How is the AP Chemistry exam scored?
The AP Chemistry exam consists of a multiple-choice section and a free-response section. Your raw scores from both sections are combined into a composite score out of 120, which is then converted into the final 1–5 AP score using the year's specific curve.
| Section | Format |
|---|---|
| Section I: Multiple Choice | 60 questions · 90 minutes (50% weight) |
| Section II: Free Response | 7 questions · 105 minutes (50% weight) |
What do you need for a 3, 4, or 5?

Frequently Asked Questions
What is a good score on the AP Chemistry exam?▼
A score of 3 or higher is generally considered passing and may earn college credit. However, highly selective colleges often look for a 4 or 5. AP Chemistry is considered one of the hardest AP classes, so a 4 or 5 is very impressive.
Are there penalties for guessing on the AP Chem exam?▼
No, the College Board does not deduct points for incorrect answers. You should answer every single multiple-choice question, even if you have to guess.
What is the hardest part of the AP Chemistry exam?▼
Many students find the Free Response Questions (FRQs) to be the most challenging because they require showing detailed work, explaining concepts in writing, and calculating multi-step stoichiometry or equilibrium problems.
