Once your AP Chemistry exam has been graded, your total score will be translated into a 5-point scale. This is done by taking a weighted combination of your total score from each section, which is then correlated to a score from 1 to 5 on the scale.

Most colleges consider a score of 3 or more while allocating college credit. Earning a college credit means that you would be allowed to 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 is translated as a weighted combination into a final score of 1 to 5. Each score is equivalent to a student’s performance level. Based on these scores, colleges decide which candidates are eligible for college credit. Currently, students need to score a 3 or above to qualify.

This scoring scale was developed after in-depth research conducted by the AP Program. The main aim of AP Chemistry is to teach you college-level foundational chemistry while you’re still in high school. Hence, the board ensures that your performance, which is measured by your final AP Chem score, can be correlated 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 take a look at what each final score on the 5-point scale equates to in terms of college grades and how each score translates to how well-qualified you might be for earning college credit.

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

As you can see, scores below 3 do not equate to a good college grade. Scoring a 4 or 5 on the exam is considered excellent, and you will most likely be eligible for college credit. However, as you can see from the table above, even a score of 3 can allow you to receive college credit.
