TEA AP® Biology

AP® Biology covers the scope and sequence requirements of a typical two-semester biology course for AP® students. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. AP® Biology was designed to meet and exceed the requirements of the College Board’s AP® Biology Framework, while allowing significant flexibility for instructors. Each section of the book includes an introduction based on the AP® curriculum as well as rich features that engage students in scientific practice and AP® test preparation. It also highlights careers and research opportunities in the biological sciences. Content requirements for AP® Biology are prescribed in the College Board Publication Advanced Placement Course Description: Biology, published by The College Board (http://ritter.tea.state.tx.us/rules/tac/chapter112/ch112d.html#112.62).
