The AP Biology exam is approximately 3 hours long, divided into two main sections:

• Multiple-Choice Section: 60 questions, 90 minutes to complete. This section tests your ability to analyze scientific data and interpret biological concepts.
• Free-Response Section: 6 questions (2 long and 4 short), also 90 minutes to complete. This section assesses your skills in interpreting experiments, graphing data, and explaining biological phenomena.

There is typically a 10-minute break between the two sections, making the total testing time about 3 hours and 15 minutes including the break
