Three practice papers
Each paper is 25 marks and 30 minutes. Sit them in order, in exam conditions, then check the mark scheme. The numbers and contexts are different on every paper.
Print every script in this topic set with the Print all papers button.
How to sit these
Close the notes. Time yourself for 30 minutes. Write on paper or print the script. Only then open the mark scheme. Do Paper 1 first, then leave at least a day before Paper 2 so you are not just remembering the numbers. Convert mA and minutes before you substitute.
