There is no expectation that students should be prepared in advance for the course or that they should buy certain books. In the Pamoja course, we use an e-textbook version of Economics for the IB Diploma (Hodder 2020). This is sufficient for students to learn from while following the course. However, should schools wish to purchase books for their library, here is a list of three textbooks that cover the IB course:
