Frequently Asked Questions

Environmental Systems & Societies (ESS) is an interdisciplinary course nestled in both the IB Science and IB Individuals & Societies groups of subjects. Students explore the relationship between humans and the planet we live on. They develop a deep understanding of the concepts of ecology and human populations and examine the impact that human resource use has on nature, with the aim of a sustainable future. The ESS SL course is interesting for students who want to make informed decisions about their impact on the environment and for those who want to study courses related to the environment after completing their IB Diploma Programme

The Environmental Systems and Societies SL course is assessed with two externally assessed exam papers at the end of the two-year course and an internally assessed individual investigation completed at an earlier time. ESS Paper 1 presents students with a Case Study of a country and asks them to analyse the data in combination with knowledge from the course. Paper 2 consists of data-based questions, short answer questions and essay questions.

Preparation for the exams should include reviewing content and practising exam-style questions. The notes that you made throughout your course should help you review the content. This can be supplemented with the Revision Village Flashcards feature, which is especially accessible on the RV Mobile App. As you finish reviewing each subtopic you can test your knowledge and skills by answering the exam-style questions RV provides for the subtopic in the Questionbank or the Popular Quizzes. This will let you know which content you need to review once again. Once you have revised all topics you can try the Revision Ladder or the Mock Exam Sets for IB Environmental Systems and Societies.

Many questions in the RV Questionbank for Environmental Systems & Societies include named examples that help you understand the content of the course. Figures for data-based questions provide interesting sets of data and naturally, we include named examples in the mark schemes of questions that require them. The RV ESS Case Studies feature is another place to learn from examples, as each Case Study includes a variety of resources on topics such as Conservation, Pollution, Food Production and more. All these materials provide examples that you could use to support your arguments on an IB ESS exam Paper 1 or Paper 2.
