Sorry to hear of your recent bad news, unfortunately, 11+ is big business and tutors are exploting the market. As a rule, I have been told that unless your child has attained a level 4a/4B and above by end of year 5, you don't stand much chance of doing well in the 11+ tests. Even if they do pass, they will struggle later on in the school. So, the fact that this tutor has gained an insight into the questions, unless the child is bright, they will struggle, the tutor, if he had morals, would tell himself whether the child will cope. Did he ask you what level he/she has attained in year 5 at school? It should have been the first question before taking on the child!
Secondly, I was under the impression that you have 5 to 6 choices on the LEA form, is Bishop Vessey different, and can be used a mock exam run? What happens if you pass the exam but fail the exam for King Edwards
