How do the scores work to get into grammar school? For example in Kent I think they have 4 exams which carry 25% of the marks each. Do they have to get a certain level in each exam or are the scores added together and taken as an average? Just wondering what happens if a child is superbright in one category say maths but not so good at another say English or vice versa? Can they get through on an average score or is a minimum required for each paper?
