Taking on AP Chemistry? You're likely trying to get a handle on the exam format and what’s expected of you. For a complete overview of the course, start with our guide on “What is AP Chemistry?.
Let's cut to the chase: the AP Chemistry exam is a single test divided into two parts. While some students refer to 'papers', the College Board calls them Section I and Section II.
Many students also wonder, "Is AP Chemistry Hard?". Knowing what's coming can make it feel much more manageable.
Let's break it all down so you know exactly what you're preparing for.
AP Chemistry exam at a glance
All AP Chemistry students are assessed on two exam sections on exam day.
Section I: Multiple-Choice Questions (MCQ)
Section II: Free-Response Questions (FRQ)
While both sections are worth 50% of your grade, they test different skills. Think of it as breadth vs. depth:
Section I covers the entire course broadly.
Section II requires you to apply your knowledge in detail.
Here's a quick comparison table to show you the main differences:
Section I | Section II | |
Question type | Multiple-Choice Questions (MCQ) | Free-Response Questions (FRQ) |
Number of questions | 60 | 7 3 long 10-point questions 4 short 4-point questions |
Timing | 1 hour 30 mins | 1 hour 45 mins |
Weighting | 50% | 50% |
Calculator allowed? | Yes (Scientific/Graphing) | Yes (Scientific/Graphing) |
Breaking down the exam sections
Let’s look at what each section demands from you because understanding the format will help you tailor your study approach perfectly!

Section I: Multiple-Choice Questions (MCQ)
Section I tests your broad knowledge of the syllabus and your ability to solve problems quickly.
Format: 60 multiple-choice questions
Calculators: Allowed
AP Chemistry Equations and Constants sheet (opens in a new tab): Provided
What it tests: Your ability to:
Recall information
Interpret data and graphs
Solve problems with speed and accuracy.
You have an average of 90 seconds per question.
The questions range from simple recall to complex, application-based scenarios.
Section II: Free-Response Questions (FRQ)
Section II is where you prove you can think and write like a chemist. It tests the depth of your understanding and your ability to think, reason, and communicate like a chemist.
Format: A mix of short-answer (4-point) and long-answer (10-point) questions
Calculators: Allowed
AP Chemistry Equations and Constants sheet (opens in a new tab): Provided
What it tests: Your ability to:
Perform multi-step calculations
Explain complex chemical concepts in detail
Apply your knowledge to new scenarios
Draw and interpret chemical models and structures
The section has 7 questions in total:
3 long-response questions (worth 10 points each)
4 short-response questions (worth 4 points each)
The questions range from straightforward calculations to complex explanations requiring detailed chemical understanding.
What about lab work & practical skills?
A common question students ask is about lab work. AP Chemistry doesn't have a formal coursework project. However, practical skills are still a huge and essential part of the course. The College Board requires that 25% of your class time is dedicated to hands-on lab work, a minimum of 16 hands-on labs (at least six of which are inquiry-based).
These practical skills are not assessed separately. They are integrated into the main written exam, especially in the Free-Response section. You will be expected to:
Analyze experimental data.
Evaluate methodologies.
Justify conclusions.
These are all skills that you build in your lab work throughout the year.
Why understanding the exam structure matters
Knowing the structure of each section is essential for effective studying. Here's why:
It allows for targeted practice.
You can focus your efforts on the specific skills each section tests.
For Section I, you need to practice your MCQ speed.
For Section II, it's all about mastering long-form answers and calculation drills.
It shapes your time management.
Understanding the timing and weighting helps you pace yourself during exams.
It also allows you to allocate your study time appropriately.
It can build your confidence.
Familiarity with the exam formats reduces anxiety.
This can help you feel more prepared and in control on test day.
It allows for strategic studying.
You can prioritize your weakest areas.
Since both sections are worth 50%, you must be strong in both MCQ technique and FRQ communication.
Frequently asked questions
How long is the AP Chemistry exam?
The total exam time is 3 hours and 15 minutes, consisting of 90 minutes for Section I and 105 minutes for Section II.
What percentage of the grade does each section count for?
Both sections are weighted equally. Section I (MCQ) is 50% of your final score, and Section II (FRQ) is 50%.
Is there a non-calculator section?
No. For the current AP Chemistry exam, a scientific or graphing calculator is recommended for both the Multiple-Choice and Free-Response sections.
What's the hardest part of the AP Chemistry exam?
This is subjective. Many students find the multi-step FRQs in Section II the most challenging due to the depth of explanation required.
