AP Chemistry Practice Test 2023 with Study Guide (UPDATED) Download printable question answers in PDF. Prepare your College Board’s Advanced Placement® Program (AP®) with our free quiz practice test.
Advanced Placement examinations (AP exams) are exams offered in the United States by the College Board and are taken each May by students. The tests are the culmination of year-long Advanced Placement (AP) courses. AP exams (with few exceptions) have a multiple-choice section and a free-response section.

The sample exam questions that follow illustrate the relationship between the course framework and the AP Chemistry Exam and serve as examples of the types of questions that appear on the exam. After the sample questions is a table that shows which skill, learning objective(s), and unit each question relates to. The table also provides the answers to the multiple-choice questions.
AP Chemistry Exam Score
The AP Grades that are reported to students, high schools, colleges, and universities in July are on AP’s five-point scale:
|AP Score||Credit Recommendation||College Grade Equivalent|
|5||Extremely well qualified||A|
|4||Well qualified||A−, B+, B|
|3||Qualified||B−, C+, C|

The AP Chemistry Exam assesses student understanding of the science practices and learning objectives outlined in the course framework. The exam is 3 hours and 15 minutes long and includes 60 multiple-choice questions and 7 free-response questions. A scientific or graphing calculator is recommended for use in Section II of the exam. No calculators are permitted for use in Section I. Students are provided with the periodic table and a formula sheet that lists specific and relevant formulas for use on the exam.
|Timing||Number of Questions||% of Exam Score|
|Section I||90 minutes||60 multiple-choice questions
*Use of a calculator is not allowed.
|Section II||105 minutes||3 long-form free-response questions
4 short-form free-response questions*Use of a calculator is allowed.

- Practice 5: Mathematical Routines 43–53%
- Practice 6: Argumentation 15–24%
A group of college and high school Chemistry instructors known as the AP Development Committee creates the AP Chemistry exam. The committee’s job is to ensure that the annual AP Chemistry exam reflects what is taught in college-level Chemistry classes at high schools. This committee writes a large number of multiple-choice questions, which are pre-tested and evaluated for clarity, appropriateness, and range of possible answers.
The free-response essay questions that make up Section II go through a similar process of creation, modification, pre-testing, and final refinement, so that the questions cover the necessary areas of material and are at an appropriate level of difficulty and clarity. The committee also makes a great effort to construct a free-response exam that will allow for clear and equitable grading by the AP readers. It is important to remember that the AP Chemistry exam undergoes a thorough evaluation after the yearly administration of the exam. This way, the College Board can use the results to make course suggestions and to plan future tests.
