your school *may* have them if they bought them or a head teacher may have them. As for getting them off the net (legally), I doubt it as they are copyright material. I think some were here on BoS but they were taken down.
@ girl04->independent schools are what some ppl call private schools. They (along with catholic schools or CCC) produce trials for use in schools. Other schools can buy them to use if they cant be bothered to make their own papers at trials time
