A-level Biology: revise the spec, not the textbook
High-yield topics, command words and the definitions examiners actually mark, with past-paper-style quiz.
High-yield topics, command words and the definitions examiners actually mark, with past-paper-style quiz.
The spec is the exam. Everything they can ask is written in it.
Cell transport, enzymes, exchange surfaces and genetics come up every year. Start where the marks are, not at page one.
Define: active transport
Movement of molecules against the concentration gradient, through carrier proteins, using energy from ATP. Three parts — examiners mark all three.
A question starts with «Explain why…». What are they marking?
«Explain» means a chain of reasons: because X, therefore Y. A definition alone scores one mark out of three — link every step.
«Describe» wants what happens; «explain» wants why; «evaluate» wants both sides and a verdict. Answer the verb, not the topic.
Enzymes after 60 °C —
Denatured: the active site changes shape and the substrate no longer fits. Never say «killed» — enzymes aren't alive, and examiners dock it.
Stop rereading the textbook. Train the questions.
Paste your own study material and Claude writes the deck on your phone.
With Pablitos, any document — or anything you ask Claude or ChatGPT — becomes training you will actually do, in seconds.
