AP® Biology – Past Free-Response Questions (2015–2025)
Explore official AP Biology free-response questions from the College Board for exam years 2015 through 2025. These past papers follow the real exam format and help students strengthen data analysis, experimental design, graphing, and written explanation skills across units such as chemistry of life, cell structure and function, cellular energetics, heredity, gene expression, natural selection, and ecology.
The AP Biology Exam is three hours long and includes 60 multiple-choice questions and 6 free-response questions, split evenly between two long and four short prompts. The free-response section accounts for half of the total exam score and emphasizes scientific reasoning using data tables, graphs, models, and experimental scenarios.
Working through multiple years of free-response questions is an effective way to practice designing experiments, interpreting statistical results, building and analyzing graphs, and connecting evidence to core biological concepts from molecules to ecosystems.
