Do they have plenty of rough paper for workings in the exam?

[Gringo64]

Hi all,

Does anyone know if they have plenty of jotting paper in the exam?

I am always encouraging my son to use rough paper to work out his answers, as he always insists on doing everything in his head. We have many arguments about this.
However, today he told me that in the Sutton mock exam, they only had one tiny piece of paper to do workings on.
Does anyone know if they have sufficient paper in the actual exams? (He is sitting the Wilson's, Sutton and Wallington exams.)

Thanks
