CHAPTER 00: About AP Biology
AP Biology is a college-level course about how living systems store information, use energy, interact with environments, and change over time. The 2027 exam framework used in this book follows the College Board AP Biology Course and Exam Description effective Fall 2025, plus the clarifications and corrections implemented through June 2026.
This introduction is your map for the whole book. It explains the exam, the units, the science practices, and the way VerityPrep questions are built. The main theme is simple: AP Biology rewards students who can use evidence, models, data, and mechanisms.
Every question in this book is original and written for the current exam. When a question refers to a table, graph, or model, that table, graph, or model is printed inside the question, exactly as it will be on exam day.
00.1 What AP Biology Studies
00.1 What AP Biology Studies
AP Biology studies living systems at multiple scales: molecules, cells, organisms, populations, communities, and ecosystems. The course is not a list of disconnected facts. It asks how structure supports function, how information is stored and expressed, how energy and matter move through systems, and how evolution explains both unity and diversity.
| Big idea | Student-friendly meaning | AP habit |
|---|---|---|
| Structure and function | Biological parts work because of their shapes, chemical properties, and interactions. | Connect a feature to an outcome. |
| Energy and matter | Cells and ecosystems transform energy and cycle matter. | Trace inputs, outputs, and limits. |
| Information | DNA, RNA, proteins, signals, and behavior help systems respond and reproduce. | Follow information flow and regulation. |
| Evolution | Populations change over generations through mechanisms such as natural selection. | Use evidence and avoid need-based explanations. |
00.2 The Exam Format
00.2 The Exam Format
The AP Biology exam is a hybrid digital exam. You read every question in the Bluebook app, answer the multiple-choice questions there, and handwrite your free-response answers in a paper booklet. An approved calculator and the official AP Biology reference sheet of equations and formulas are allowed.
| Section | Format | Timing | Weight |
|---|---|---|---|
| Section I | 60 multiple-choice questions (A-D). Some are discrete; others come in sets of about 4 to 5 questions that share one graph, table, model, or experiment. | 90 minutes | 50% |
| Section II | 6 free-response questions: 2 long questions (9 points each) and 4 short-answer questions (4 points each) | 90 minutes | 50% |
Exam at a glance. Section I gives you about 1.5 minutes per question. In Section II, a practical budget is about 25 minutes for each long question and about 10 minutes for each short question.
