We have exactly the same with our son and got exactly the same repsonse. We have left him where he is as he does have some friends and the school is catering for him for some non-academic areas( he is a gifted sculptor/artist) and we hope he will be mature enough to cope.
Someone on this site once told me that with his profile a good social/educational match would be near impossible and we would have difficulties (I think it was Dottie ?) - and boy was she right. But our son is fairly happy and progressing and we do a lot of stuff outside the curriculum (extension stuff?) at home. This seems to be working fairly well, but it does get fraught with the school at times.
