Choose how to study

Work on a calculation, revisit a mechanism or apply what you know. Start with the part you need today.

Try a short session, check your working and revisit the questions you missed.

Plan a comparison, calculate from example readings and evaluate what the evidence supports.

Put the steps in order, find a missing link and explain the biological consequence.

Form an answer, reveal the explanation and keep the cards you want to practise again.

Choose relevant examples and connect their mechanisms to the exact essay title.

Use a case and its data to draft an explanation, then compare and review your response.
