11 May IB ESS Study Plan: A Weekly Workflow for SL and HL
An IB ESS study plan should reflect your level, examination session, school deadlines and current gaps. A useful weekly workflow combines understanding concepts with applying them to data and environmental issues. Treat the schedule below as an adaptable suggestion, not a promise of a particular grade.
Start with the correct assessment requirements
For the course first assessed in 2026, SL Paper 1 contributes 25%, Paper 2 contributes 50%, and the IA contributes 25%. At HL, the corresponding weightings are 30%, 50% and 20%. HL also includes environmental law, environmental and ecological economics, and environmental ethics lenses.
Use the current SL and HL syllabus guide to check formats. An older past paper may practise a relevant concept, but it does not reproduce the current assessment structure.
Build a short skills inventory
Choose a recent school task or a practice question. Identify what made it difficult: recalling a concept, reading a graph, performing a calculation, explaining a process, applying a case study or reaching a supported judgment.
Keep a record of the specific difficulty and the next action. “Read everything again” is less useful than “practise interpreting percentage change and explain what the data can support”.
An adaptable weekly workflow
| Session | Suggested task | Evidence to review |
|---|---|---|
| Concept review | Explain one process in your own words, then check it against course materials. | Missing links or inaccurate terms |
| Data practice | Interpret a graph or table and complete a relevant calculation. | Units, working and evidence used |
| Case study application | Compare a management strategy’s benefits and limitations. | Relevant stakeholders and a justified judgment |
| Exam practice | Attempt selected questions, then review the applicable markscheme. | What answered the command term and what did not |
| Weekly review | Revisit errors and set the next priority. | Whether the earlier difficulty is now resolved |
Use shorter sessions when other subjects are demanding. Add timed practice gradually, once you understand the relevant content. A full paper is useful only if you also make time to review it.
Plan the IA separately
Work backwards from your school’s deadline. Set milestones for the question, strategy, method, data collection or sourcing, treatment, analysis and evaluation. Allow time to resolve practical problems before writing the final report.
The current IA can use appropriate primary or secondary data. It is not necessary to run a new experiment every week. Follow the IA workflow and keep the investigation and writing your own.
Adjust the plan using feedback
If you can recall definitions but struggle with an unfamiliar resource booklet, give more time to data interpretation. If your extended responses describe an issue without evaluating it, practise linking evidence to a reasoned conclusion.
At HL, include relevant lens applications. Check progress through specific tasks and school feedback rather than assuming that hours studied automatically translate into a grade increase.
Practise with individual ESS support
In Marija’s online IB ESS SL and HL lessons, you can work on concepts, data interpretation and clear explanations. Request a free 20-minute trial lesson to discuss your priorities. For IA work, the investigation and submitted writing remain your own.
