FAQs

How should learners use the study pack for a triple-only topic?

The pack explains which part of the specification learners are studying and that it indicates when a topic is a triple-only topic. It then guides learners to work through relevant “prove it” questions and check answers using the revision guide.

What are GCSE command words and how are they used in exam questions?

The pack lists common command words with definitions and examples, showing how different tasks require different styles of responses (e.g., state, describe, determine, explain, evaluate, compare, sketch).

Which biology topics are covered in Biology Paper 1 and Biology Paper 2?

Biology Paper 1 covers cell biology, organisation, infection and response, and bioenergetics. Biology Paper 2 covers homeostasis and response, inheritance variation and evolution, and ecology.
