In June 2018, an A* in Edexcel A Level Biology B (9BI0) needed 197 marks out of 300 (66%), an A needed 167 (56%) and a pass at E needed 64 (21%). At AS (8BI0), an A needed 93 out of 160 (58%).
All marks below are raw marks from Pearson's published grade boundaries. Your grade comes from your total across the papers; the boundaries for each paper are Pearson's notional component boundaries, a guide to how you did on that paper rather than a separate grade.

How to use these grade boundaries
- Sit the June 2018 paper timed, then mark it strictly with the mark scheme.
- Check your raw mark against the boundaries for that paper above to see roughly where you are.
- Read the examiners' report for every question where you dropped marks.
Boundaries move from year to year as papers get harder or easier. See how they compare across every year.
