What is AP Bio?
Before we delve into the second season, it’s important to understand the premise of the show. AP Bio centers around Jack Griffin, a disgraced Harvard philosophy professor who, after losing his dream job, is forced to teach Advanced Placement Biology at a high school in Toledo, Ohio. However, rather than teach biology, Jack uses the class for his personal gain—manipulating his students to help him exact revenge on those who wronged him.
The show blends sharp humor with themes of personal growth and human relationships, all while focusing on the hilariously dysfunctional relationships between Jack and his students, as well as the various faculty members.
