AP Biology Exam Overview
The AP Biology Exam assesses your comprehension of the biology topics taught in the course, as well as your ability to apply the scientific method and analyze data. You may use a four-function calculator (with square root), as well as scientific or graphing calculators during this exam.
AP Biology Exam Sections
The exam lasts for 3 hours in total and consists of two sections:
Section 1: Multiple Choice
- 60 questions, 1 hour and 30 minutes.
- This section includes individual questions as well as sets of questions with 4–5 questions per set.
Section 2: Free Response
- 6 questions, 1 hour and 30 minutes
- There are 2 long questions and 4 short questions. Long questions are worth 8-10 points each; short questions are worth 4 points each.
- The long questions ask students to interpret and evaluate experimental results, with and without graphing.
- The short questions assess students’ understanding of scientific investigation, conceptual analysis, analysis of a model or visual representation, and data analysis.
AP Biology Exam Scoring
The AP Biology Exam is graded on a scale of 1 to 5, with 5 being the highest possible score. The scoring is divided as follows:
- Multiple Choice: 50% of the total exam score
- Free Response: 50% of the total exam score
After calculating all raw scores, they are converted to the 1 to 5 scale, taking into account the difficulty of each exam to ensure a fair comparison across different years.
Average scores for the AP Biology Exam can fluctuate annually. In 2023, the average score was 3.04, with a score of 3 or higher generally considered passing.
The distribution of scores for the 2023 AP Biology exam is detailed below:
| 5 | 4 | 3 | 2 | 1 | 3 or Above |
| 14.3% | 23% | 27.2% | 23.6% | 12% | 64.4% |
AP Biology offers an exciting opportunity to deepen your understanding of life sciences while earning college credit. By familiarizing yourself with the course content, honing essential skills, and preparing effectively for the exam, you can set yourself up for success.
AP Transfer Credit
For several universities in the US, you can transfer your AP credits if your score is 4 or 5. You can find more details in the table below.
| AP Score | Credit Recommendation | College Grade Equivalent |
| 5 | Extremely well qualified | A |
| 4 | Well qualified | A-, B+, B |
| 3 | Qualified | B-, C+, C |
| 2 | Possibly qualified | n/a |
| 1 | No recommendation | n/a |
By mastering the material and performing well on the exam, you open doors to advanced academic opportunities. Be sure to review all the key topics, practice thoroughly, and explore your options for earning college credit.
