FRQ Question Types
Multi-part questions integrating multiple Science Practices. Q2 always requires constructing a graph. Typical structure: describe trend → explain mechanism → predict / justify → design follow-up.
- Allocate ~25 minutes each
- Spend 2–3 min planning before writing
- Use CER framework throughout
Each short FRQ tests a specific skill. They appear in a fixed order on every exam.
- Q3 — Scientific investigation design
- Q4 — Conceptual analysis & explanation
- Q5 — Model or visual representation
- Q6 — Data analysis & interpretation
