Whether you're a current IB Economics student looking to get a deeper grasp of the syllabus or a prospective IB student weighing your Group 3 options, this post will be your guide. We'll break down the IB Economics syllabus to give you a clear understanding of what to expect in the course.

The IB Economics syllabus is divided into four Units:
