Criteria Feedback
- The student's exploration has a clear overall progression from context to modelling, comparison, validation, and conclusion.
- The report is well structured and easy to follow, with sections that guide the reader through the student's process.
- The student's topic stays relevant to the investigation, and the forecasting check adds meaningful purpose to the work.
- Some conclusions are stated more confidently than the evidence supports.
- Several sections repeat similar explanations, which makes the report longer than necessary.
- A few figures and references could be organised more consistently.
