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.
