I have a DS who is currently at a well known tuition centre for 11+ tuition. It's ok but we feel that because of the large group classes he isn't making much progress and gets little time with the tutor and some areas are difficult, so we are looking for one-to-one tuition. In West London (Pinner, Harrow, Ruislip, Uxbridge etc) good tutors are very hard to come by so could anyone recommend someone?
