These new IB ESS Case Studies have been designed for you to apply your knowledge and understanding of Environmental Systems & Societies in challenging Paper 1-style contexts. Each Case Study provides you with a range of materials about a country or region and a set of questions of varying levels of difficulty. A complete markscheme identifies the ESS concepts and terminology required to achieve the marks and a sample answer allows you to see how this could be compiled into a good response. The Case Studies are organised into themes taken from the Environmental Systems and Societies SL concepts: four themes focusing on nature and four on humans. All the Case Studies are written in a Paper 1-style; our team of experienced IB ESS teachers and examiners have created both full-length and shorter examples as well as three levels of difficulty to suit a range of revision needs.

Original Case Studies to train the skills in analysing and evaluating data that you need for Paper 1. 

Develop your understanding in IB ESS SL using custom-built flashcards, perfect for quick study sessions on desktop or mobile app.
