The rules for the day
Pearson's specification mentions calculators only as a skill a candidate may be tested on and prints no permission sentence, so we do not state one here. Ask your school or college, or read the instructions on the front of the paper itself, which set the rule on the day.
To see which lesson teaches each heading of the specification, use the Pearson Edexcel Biology B specification map.
We checked these links against the exam boards’ websites on 6 September 2026. We do not host or reproduce past papers or mark schemes. If a link has moved, go to the board’s own past papers page.
