the teacher had to admit to me.
He doesn't really contribue in the class - fair enough she's not too worried about that - some people just don't like contributing in large groups - she admits she's one of them - fine with a class of 30 children but put another adult in the room and she crumbles (and I'm pretty much the same)
However he also doesn't work quickly enough so doesn't finish his work so she can't see that he's understood the stuff either.
He's so obsessed with perfection (neatness) that he spends ages writing things down and then doesn't get a chance to finish it
So she thinks he's doing well but couldn't say with total confidence
