ESS Checklist

To effectively prepare for the IB Environmental Systems and Societies (ESS) course, begin by obtaining the most recent subject guide—either as a printed copy or in digital format. Focus particularly on the syllabus content section, which details the core topics, subtopics, and associated understandings, applications, and skills required by the curriculum.

You may choose to work directly with the printed specification by highlighting and annotating relevant sections, or alternatively, convert each syllabus statement into a revision-friendly checklist. For example, statements such as “Explain how feedback loops regulate natural systems” or “Evaluate strategies for pollution management” can be rephrased into actionable revision prompts. This approach helps clarify what is expected and enables more targeted studying.

As you work through each topic, apply the RAG (Red–Amber–Green) rating system to assess your level of understanding:

Red: Topics you do not understand.

Amber: Topics you understand partially or require further review.

Green: Topics you feel confident with.

You can indicate these ratings using colored pens, highlighters, or stickers on a printed copy of the syllabus. If you prefer a digital format, you can build the checklist in a document or spreadsheet and apply digital equivalents of the RAG system. Be sure to update your ratings regularly based on classwork, completion of past paper questions, and teacher feedback.

Prioritize revision of Red and Amber-rated areas to ensure consistent progress across the syllabus. It is also essential to pay close attention to the IB command terms used in each syllabus statement, as these indicate the required depth and style of your responses. This structured approach helps ensure your revision remains focused, comprehensive, and aligned with the specific demands of the IB ESS course.
