However, it has gone against her. I have just had her report and even though she has got A* in the science, Geography, Spanish, ICT and History exams - A's in all her other subjects and x1 B in MATHS.
I think that you need to be very careful complaning that DD ONLY got 6 A*, 1 B and the rest A's - This is an excellent set of results and worthy of a high level of commendation and praise to your DD. To be honest, I think that you have very little to worry about, if DD gets GCSE result like this then she will be able to choose whatever she wants to do for A Level
I would be delighted if DS came home at the end of year 7 with a set of results like this!
The problem that she has faced is, the teacher ASSUMES that all the kids know alot already and has skipped the basics. Which is true for the tutored lot - most of them are probably just below GCSE standard in year 7! - but for non tutored kids it's like trying to build a house without the foundations!
My DS was tutored for 1 hour per week for 6 months, and we know many kids who were tutored. In my experience, tutors do not go beyond the 11+ sylabus - yes they may cover some subjects such as Algebra, which is not covered at primary until later in year 6. The fact that your DD passed the 11+ would indicate that she had as good a level of Maths as the other tutored kids who passed the exam. The fact that she got a B also indicates that she is not really struggling too much either!
I have heard the comment that an 11+ pupil could pass a GCSE - probably with a low grade such as an "E" - GCSE maths is really easy at the lower end
