Paper 1 — Required practicals (overview)
How required practical questions are asked, and the checklist for full marks.
Required practical questions: what examiners want
Use this checklist:
- Aim (what are you investigating?)
- IV / DV
- Control variables (and how you control them)
- Method steps (clear, replicable)
- Risks + safety
- How you calculate rate / mean / % change
- How you improve reliability (repeat + mean)
- How you improve validity (control confounders)
