The AP® Chemistry exam has two sections. Each section accounts for 50% of the overall score. Section I includes 60 multiple-choice questions, while Section II has seven free-response questions. Of the 7 questions in Section II, 4 are short-answer questions, and 3 are long-essay questions.

Let’s look at the scoring methodology for each section.

Your final score is on a 5-point scale related to your point tally. A weighted combination of your total score from each section converts to a score from 1 to 5 on the scale.

Many colleges consider a score of 3 or more while allocating college credit. Earning a college credit means you could skip an equivalent college-level foundational course in chemistry during your first year.

AP Chemistry Scoring Table

As you know now, your total score on the AP Chem exam translates to a weighted combination into a final score of 1 to 5. Each score is equivalent to a student’s performance level. Colleges decide which candidates are eligible for college credit based on these scores. Currently, students need to score a 3 or above to qualify.

This College Board® developed the AP scoring scale after conducting in-depth research. The main aim of AP Chemistry is to teach you college-level foundational chemistry while you’re still in high school. Hence, this scoring system ensures your performance on the exam correlates to a college student’s performance in a college-level chemistry course.

“Only two students got a perfect score on the AP Chemistry May 2021 exam.”

Let’s explore how each score translates to how well-qualified you might be for earning college credit. Each final score on the 5-point scale equates to college grades as indicated below.

AP Chemistry Score Qualification College Grade Equivalent
5 Extremely well qualified A+ or A
4 Very well qualified A-, B+, or B
3 Qualified B-, C+, or C
2 Possibly Qualified
1 No recommendation

Scoring a 4 or 5 on the exam is considered excellent, and you will most likely be eligible for college credit. At many schools, a score of 3 may also earn college credit. Though colleges typically only give credits for scores of 3 or higher, research by the College Board shows that students who earn a 2 are well prepared to succeed in introductory coursework and tend to perform better in those courses than their peers who did not take AP Chemistry.
