My DS started at s grammar school, by default in September on the sibling rule we have just accepted a place for my daughter at the girls grammar. She took the 11+ but we didn't tutor her as long and she came in just under the required level for entry on academic grounds only. But we are in a pickle, for various reasons we are not happy with the boys grammar and have looked to pull DS out before it's too late. But we've just read the small print which says he needs to be attending the school when our DD starts in September or her place could be withdrawn. Is there anything we can do?
