AP Biology

AP Biology is an introductory college-level biology course. Students cultivate their understanding of biology through inquiry-based investigations as they explore topics like evolution, energetics, information storage and transfer, and system interactions.

AP Biology Course and Exam Description

This is the core document for this course. It clearly lays out the course content and describes the exam and the AP Program in general. The CED was updated in the summer of 2020 to include scoring guidelines for the example questions.

AP Biology CED Errata Sheet

This document details the updates made to the course and exam description (CED) in September 2019. It includes printable copies of the updated pages, which can be used as replacement sheets in your CED binder. Note: It does not include the scoring guidelines, which were added to the online CED in the summer of 2020.

AP Biology CED Scoring Guidelines

This document details how each of the sample free-response questions in the course and exam description (CED) would be scored. This information is now in the online CED, but was not included in the binders teachers received in 2019.

AP Biology: Equations and Formula Sheet

Students are allowed to use this resource on the AP Biology Exam. It is also available in Appendix A of the CED.

Course Content

Based on the Understanding by Design® (Wiggins and McTighe) model, this course framework provides a clear and detailed description of the course requirements necessary for student success. The framework specifies what students must know, be able to do, and understand, with a focus on the big ideas that encompass core principles, theories, and processes of the discipline. The framework also encourages instruction that prepares students for advanced work in STEM majors.

The AP Biology framework is organized into eight commonly taught units of study that provide one possible sequence for the course. As always, you have the flexibility to organize the course content as you like.

Unit 6: Gene Expression and Regulation

Unit 7: Natural Selection

Science Practices

The AP Biology framework included in the course and exam description outlines distinct skills, called science practices, that students should practice throughout the year—skills that will help them learn to think and act like biologists.
