All six papers are Challenge level. Biology has no standard mocks — every paper
below is deliberately harder than a real Cambridge paper, so there is no easy option to pick.
Read your scores in that light: a mark that looks low here would normally be higher on the real thing.

All three papers cover the whole topic. Like a real Cambridge paper, each one ranges across every sub-topic — they differ in the angle they come at it from, not in what they cover. The notes under each are just where that paper leans hardest.
