past papers are fine but a bit boring to do them day in day out (not that he has)
To say 'what is wrong with book" is just plain silly - websites have been developed, kid are computer literate and why not sue them?
or do you not use a dishwasher or washing machine - because fgs - what is wrong with hands?...
anyway he is aiming for A* - a year early and needs to revise specific stuff. He does one past paper a week - is enough I think!!
