Do you mean the boys one Kings Grammar school or the girls one Grantham and Kesteven school. My Dd actually goes to Walton but has friends at both, they both have a good reputation and as far a I know the boys school take the top % that pass regardless of where they live. So for example a boy could live in Grantham with a score of 225 (pass mark is 220) and a boy live in Nottingham and get 227 and he would get in above the boy who lives in Grantham . Hope that helps a bit
