DS 15 is in gcse year. He is a good kid in most ways...can be argumentative at times but I can accept it’s part of growing up. Just been to parents evening recently and they pretty much all told me he’s capable of doing well ( you think I’d be happy) and I am to a point. The thing is he could do really well but he is putting little or no effort into revision. He goes up to his room and says he’s revising but I had suspicions He wasn't and have seen messages on his phone to friends saying he can’t be bothered and will be happy with lvl6’s even though he’s capable of 7 and 8’s. This is not him just saying this to his mates as the one he was messaging was saying how much he’d done.
I’m worried he won’t get what he’s capable of and will regret it but if I mention anything that’s when I get the back chat and stop hassling me type of response. I’ve bought him loads of revision type stuff to help him and will do anything to help him succeed but I can’t do it for him. Any suggestions?
