Review the processes and principles behind living organisms and their ecosystems through exam prep practice questions on scientific inquiry and models in Albert's AP Biology prep course. Before 2012, the AP Biology test had 100 multiple-choice questions and four free-response questions rather than the current 63 multiple-choice questions, six grid-in questions, six short free-response questions, and two long free-response questions. The old test was also more memorization-based. Starting with the 2024 exam, the layout for the free-response questions (FRQs) will be different from prior exams. For a summary of the changes, and to help you visualize this change to the layout, we’ve applied the 2024 layout to the 2021–2023 AP Biology FRQs. You can find the original scoring guidelines on the past exam questions page.
