GCSE Functional Question Booklet Edexcel Specification B Mathematics Unit 2 This booklet has been produced to help with the functional questions in your exam. These are often labelled with an asterix * and require you to use written English to explain the solution you have arrived at. They are worth anything from 4 up to 6 marks and require you to show all of your working out. At all times, you must make clear what it is that you are working out.
