Tips

Practise the data-analysis questions first. They are the most transferable part of the paper: the skill you build on one graph works on the next, whatever the organism.

Answer in the required form. A prompt that says "describe" wants what happens; "explain" wants why; "justify" wants evidence from the data given. Confusing the three is the commonest avoidable loss on this paper.

Older released papers use the previous unit numbering but the science practices they test are unchanged — they are still good practice for exactly the skills that decide the grade.
