ESS past papers can strengthen your revision when you choose questions that fit your current course. Learn which older tasks to use and what to check before a mock.

Reviewed 4 October 2026 · Current ESS SL and HL course, first assessment 2026.

ESS past papers can help you practise reading questions, interpreting data and explaining environmental ideas. Before using a paper, check its examination year, syllabus and level. A useful old question is not necessarily a suitable full mock exam for the current course.

Check the current SL and HL format first

The previous version of this page described an older SL assessment model. For current timings, marks, weightings and essay choices, use the ESS Paper 1 and Paper 2 assessment overview for SL and HL, checked against the official IB ESS guide.

How to use ESS past papers

1. Match the topic. Compare the content of the question with your current course notes and teacher’s guidance.
2. Check the task. Identify the command term, context and mark allocation before answering.
3. Practise a transferable skill. Graph reading, calculations and evidence-based explanation can be useful even when the full paper format is outdated.
4. Use the matching markscheme. Review the reasoning and omissions in your answer, not just its length.
5. Record one improvement. Note a specific change such as adding units, using a data value or explaining a causal link.
6. Retry later. Revisit the skill in a different question to check that you can apply it independently.

Do not use an old paper as a current mock without checking it

A legacy paper may omit current content or use different essay choices and mark totals. This matters especially when preparing for HL. Ask your teacher for current specimen or examination materials for your level and use those for full timed rehearsals.

Make a distinction in your revision notes: “old topic practice” for selected questions, and “current-format mock” for a complete suitable paper. That prevents an old timing or assessment pattern from becoming your exam-day plan.

Paper 1 and Paper 2 practice

For case-study work, use the Paper 1 preparation guide. For short answers and structured essays, see Paper 2 strategies for SL and HL. If your answer does not address the task, practise ESS command terms before writing a longer response.

Where to start

Ask your school teacher which current papers and markschemes are available to your class. This page explains how to use practice materials; it does not provide downloads of official exam papers.
