Questions & AnswersIf you have any other questions - please get in touch

What is the AP Biology exam format?

The exam format includes 60 multiple-choice questions, and 6 free-response questions. Both the multiple choice section and the free response questions take up 50% of the exam's weight. Students are allotted 1 hour and 30 minutes to complete the multiple-choice section, and 1 hour and 30 minutes to compose their responses to the free response questions. To make sure you’re prepared enough to finish in time, take a look through our free AP Biology study guide that covers the most important material you should know.

How do I study for AP Biology?

You’ve likely covered a lot of material during your course this year, but to get a 5 on the AP exam, it’s important you understand how often each topic shows up. This class will involve immersive laboratory experiences, where you will actively investigate and analyze natural phenomena firsthand. Once you take a look through the breakdown below, make sure to read through the AP Biology study guide above with all the key points you should know for each unit.

What units are on AP Biology?

Unit 1: The Biochemistry of Existence
During this unit, you will begin an exploration into the crucial role of water as the foundation of life, as well as begin an understanding of the roles and functions of macromolecules such as lipids and proteins.
Unit 2: Exploring Cellular Structure and Function, and the Fundamentals of Evolution
In this unit, you will begin a comprehensive study of cellular composition, diving deep into the architecture that defines cells. Additionally, you will also immerse yourself in the fundamental concepts of evolution, unraveling the mechanisms that makeup the diversity and development of life forms over time.
Unit 3: Investigating Cellular Energetics and Interactions with the Environment
Within this unit, you will begin to investigate the study of cellular energetics, diving into understanding the mechanisms that govern how cells harness and utilize energy. Additionally, you will begin to understand how cells interact in tandem with their environment, understanding the biological processes that operate at the cellular level.
Unit 4: Cellular Communication, Growth, and Reproduction
In this unit, you will gain an in-depth understanding of the processes that control cell growth and reproduction. Also, you will understand the complex world of cellular communication, unraveling the mechanisms through which cells interact and coordinate their activities.
Unit 5: Exploring Heredity and the Transmission of Traits across Generations
During this unit, you will delve into the complex mechanisms that control the passage of traits from one generation to the next. Through a well rounded exploration, you will gain a profound understanding of how genetic information shapes the characteristics of living organisms over time.
Unit 6: Investigating Gene Expression, Transmission, and Regulation of Hereditary Information
Within this unit, you will engage in an in-depth study of the processes through which hereditary information is transmitted from parents to offspring. Additionally, you will begin to explore the world of trait expression, unraveling the mechanisms that govern how genetic traits manifest in living organisms.
Unit 7: Natural Selection
In this unit, you will dive into the comprehensive study of natural selection, immersing yourself in the intricacies of Darwin's groundbreaking theory. Additionally, you will gain a profound understanding of the concept of evolution, unraveling the mechanisms through which species adapt and change over time.
Unit 8: Ecology
Within this unit, you will embark on an extensive exploration of ecological principles, expanding your understanding of biological concepts beyond the cellular level. You will gain insights into the intricate interactions that shape populations within ecosystems, contributing to your comprehension of the delicate balance of life within these intricate biological communities.
