This innovative text emphasizes biology's major concepts and provides students with opportunities to apply those concepts through data analysis and active-learning.

The new teacher's edition - written for and by AP Biology instructors - is designed to support every AP Biology teacher using POL teach a successful course and prepare their students for the redesigned exam.
