How to use the Biology SL question bank

This bank contains 1,548 questions drawn from 87 real past papers, covering 2016-2025. Use it to isolate weak topics before switching to timed whole-paper practice.

Choose one topic. Start narrow enough that mistakes reveal a specific gap.
Filter deliberately. Use year, paper, marks, and other filters to control difficulty and format.
Check, record, repeat. Review the mark scheme, note the cause of each lost mark, then retry a similar set.
