My DS is 14, just gone into year 10. He does ok at school but as with most kids, could do better/needs to work harder. He doesn't get much homework so is usually on his laptop playing games from when he gets in until bedtime. I have asked him to do half an hour revision each night before he goes on the laptop. He's never going to do it off his own back - I am going to have to set him a timetable - and he will do it. My question is - do you think this is reasonable/enough? Should I be more harsh with the time he can spend on his laptop?
