Tips
Mark these against the scheme phrase by phrase. IGCSE Biology schemes award named points, and an answer that says the right thing in loose language repeatedly earns one mark where three were available. Underline the exact words that earn each point.
Do the diagram questions with a pencil and no notes. Labelling a heart, a leaf section or a digestive system from memory is directly examinable and is the fastest thing to strengthen — you find out in seconds whether you know it.
The practical papers are worth attempting early. They test whether you can read a result and say what it shows, which improves independently of how much content you have covered.
