Just that really , ds3 is in the top set for maths , they will all do IGCSE at the end of year 11 . It's a selective ( though with a long tail) so the whole year group will do the same exam.
I'm happy with this providing there is plenty of sideways non examined stretch to keep him interested but I notice that a lot of the schools do either ad maths or statistics and I am wondering what the advantage of this is or if he is at a disadvantage in not doing these extra qualifications .
