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 this page does not claim one. Ask your centre, or read the instructions printed on the front of the paper itself, which is where the rule that binds on the day appears.
Candidates must use an unmarked copy of the Data Booklet in examinations.
