Do you know your National Insurance number? I know mine, my wife spent ages before she found something  with her number on.
My wife has just shown me what pupils will have to do to produce the proof they would have on their green counterpart.
None of my pupil have printers therefore when they attend for their test are the examiners  going to stand there while they trail through this information on their mobiles?
Someone tell me I've got this all wrong.
