Whether you're a current IB Biology student looking to get a deeper grasp of the syllabus or a prospective IB student weighing your science options, this post will be your guide. We'll break down the IB Biology syllabus to give you a clear understanding of what to expect in the course.

The IB Biology syllabus is divided into four themes:

• Theme A: Unity and diversity
• Theme B: Form and function
• Theme C: Interaction and interdependence
