A Snapshot of The AP Statistics Exam
Advanced Placement (AP) courses bring college-level course content and rigor to high school classrooms in the US. Each course comes with a corresponding assessment. Curricula and exams are governed by the College Board.
While taking the formal assessment is optional, a high score is a sign of college readiness and can even earn you college credit in that subject in US and Canadian universities.
In addition, a high score on any AP exam can elevate your university application profile, constituting a distinct marker of academic ability and spotlighting advanced academic rigor on your high school transcripts.
The AP Chemistry Exam tests your chemistry knowledge across a wide range of fundamental principles and skills, including:
- Explaining, analyzing, or interpreting chemical properties or phenomena
- Testing or evaluating a hypothesis or prediction using scientific methods and scientific reasoning
- Using graphs and data to represent chemical phenomena
- Applying math-based problem solving
Exam Duration:
The exam lasts 3 hours and 15 minutes.
Calculators Allowed?
Starting with the 2023 exam, a scientific or graphing calculator is recommended for use on both sections of the exam.
Key Elements:
The AP Chemistry Exam has consistent question types, weighting, and scoring guidelines every year.
Section I. has 60 Multiple Choice Questions (MSQ) which count for 50% of the total score.
Section II. has 7 Free Response Questions (FRQ), counting for the remaining 50% of the total score.
The FRQs assess all 6 of the course skills:

The questions consist of 3 long-answer questions, for 10 points each, and 4 short-answer questions, for 4 points each.
With this overview in mind, let's delve into the core content covered on the exam.
What's Covered on the AP Statistics Exam?
The AP Chemistry Exam revolves around 4 Big Ideas guiding AP Chemistry course content.
| BIG IDEA 1: SCALE, PROPORTION, AND QUANTITY (SPQ) | BIG IDEA 2: STRUCTURE AND PROPERTIES (SAP) | BIG IDEA 3: TRANSFORMATIONS (TRA) | BIG IDEA 4: ENERGY (ENE) |
|---|---|---|---|
| Quantities in chemistry are expressed at both the macroscopic and atomic scale. Explanations, predictions, and other forms of argumentation in chemistry require understanding the meaning of these quantities, and the relationship between quantities at the same scale and across scales. | Properties of substances observable at the macroscopic scale emerge from the structures of atoms and molecules and the interactions between them. Chemical reasoning moves in both directions across these scales. Properties are predicted from known aspects of the structures and interactions at the atomic scale. Observed properties are used to infer aspects of the structures and interactions. | At its heart, chemistry is about the rearrangement of matter. Understanding the details of these transformations requires reasoning at many levels as one must quantify what is occurring both macroscopically and at the atomic level during the process. This reasoning can be as simple as monitoring amounts of products made or as complex as visualizing the intermolecular forces among the species in a mixture. The rate of a transformation is also of interest, as particles must move and collide to initiate reaction events. | Energy has two important roles in characterizing and controlling chemical systems. The first is accounting for the distribution of energy among the components of a system and the ways that heat exchanges, chemical reactions, and phase transitions redistribute this energy. The second is in considering the enthalpic and entropic driving forces for a chemical process. These are closely related to the dynamic equilibrium present in many chemical systems and the ways in which changes in experimental conditions alter the positions of these equilibria. |
Take AP Chemistry for Mastering Content
With a high enough score on your AP Chem exam, you'll be able to skip over introductory chem courses in college! And, and even if you don't score well, taking AP Chemistry is a great way to build your science foundations for greater success in college.
