Are you going to meet with teachers before end of term? I saw your other thread about his maths, doesn't sound right.
My DDs maths, English and science isn't the problem, she has done ok in those -
English 6c, target 7c,
Maths 7c, target 6a
Science 7b, target 6a
Although English isn't great I'm not too worried about that as I think a target of 7c is a bit high for her.
It's all the other subjects I'm fretting about - low levels 5s in everything with poor grades for effort, mostly 3 meaning 'requires improvement'.
Interestingly the three subjects she is doing ok in are streamed, the others aren't and I think she spends the time chatting and doing the bare minimum.
This is a standard London academy. Let's hope a rest during the hols will help them go back to year 9 and buckle down.
