In November 2021, an A* in Edexcel A Level Biology B (9BI0) needed 176 marks out of 300 (59%), an A needed 142 (47%) and a pass at E needed 41 (14%). At AS (8BI0), an A needed 87 out of 160 (54%).
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.
There were no summer exams in 2021 (grades were teacher-assessed). Pearson ran an autumn series in November 2021.

How to use these grade boundaries
- Sit the November 2021 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.
