Leave him to it, let him fail and learn from his own mistakes?
Take away that bloody iPod touch unless all revision and homework is done?
Background: I have nagged and nagged, I admit it. I have spoken to him calmly. I have actually cried, I've been so upset.
Nothing works. He leaves his school work to last minute, doesn't revise for tests. Not bothered when he doesn't do well. Often blames me or his dad for not helping him. However, he doesn't even try to do a small bit of the work himself, and his dad won't help unless he shows willing to make a modicum of effort.
