He's got end of year tests in the next couple of weeks and getting him to do any work for them is practically impossible. He reluctantly sits and does 5 mins then thinks he's done enough, claims he knows it all. He is doing very well at school despite his lack of work at home. Parent's eve was all good and high targets in all his subjects. Should I leave him to it? Surely he has to knuckle down at some point. I just don't know how to get through to him that you reap what you sew. He's so laid back about it all. Arrrghhh!
