Revise by Topic
By topic, not by paper.
Every question is tagged with the themes RHS examiners reach for over and over. Start with the ‘very common’ row — that's where most marks live.
Photosynthesis & Limiting Factors
3 QWord equation, light/CO₂/temperature as limiting factors, glasshouse applications.
ReviseSoil Science
6 QTexture, structure, pH, hand-texture test, soil management.
RevisePlant Nutrition (NPK & deficiencies)
6 QRoles of N, P, K, deficiency symptoms, iron lock-up in alkaline soils.
ReviseBiosecurity & Plant Passports
3 QPlant passports, quarantine pests, hygiene, sourcing healthy stock.
ReviseSustainability & Peat-Free
4 QPeat-free media, water conservation, green manures, environmental impact.
RevisePlant Establishment & Tree Planting
