Economics Made Simple — The Complete Bundle
The Complete Bundle brings together everything we have built for AP and Cambridge A-Level Economics students: the full 914-page supplementary textbook, a 450-question practice workbook with mark schemes, a rapid-revision flashcard deck, and 100 real-world case studies with expert analysis. Four products, one price — designed to take you from first principles to exam-ready.
Most students use the textbook to understand the theory, the practice questions to test themselves under timed conditions, and the flashcards in the final week before the exam. The case studies sit alongside both — every concept grounded in something that actually happened, from carbon pricing in Sweden to the 2008 financial crisis. It is the study system we wish we had when we were students.
