Op, I can't help thinking after some ofthe things you have said about your child that they really will be better off in school.
It was you on a different thread that talked about "they like string theory, what other topics could i dangle in front of my child to see if they bite"
in the opening post, wasn't it? ( or words to that effect)
you must know dangling topics in front of a child to see if they bite is absolutely no way to go about educating a child at all,
and in the same thread you mentioned that your child has an island of ability in maths, but no scientific thinking skills, imagination or originality at all.
I think the very unusual way you talk about your child, the extremely uneven pattern of abilities you describe and the unrealistic expectations you have are all significant concerns.
I hope your child starts school full time this September, they really are going to be so much healthier and happier there.
