It's a running battle here and it has to stop.
I think he doesn't spend enough time on his homework or produce enough, he thinks I expect too much. e.g. He rarely sits for more than 20 mins on an essay.
He has a History assessment to do this weekend. He's been told it's going to be marked like a piece of GCSE coursework.
How long should it take and how much should be produce in that time? I know it's not all about quantity but that gives us a place to start.
If it's relevant he is working at levels that mean he should get his 5 A-C but he won't be one of the 8 A* gang.
