Ah, I had to take one of those tests once. I was 13 and desperately wanted to be moved up a year at school because I was being bullied in the year I was in and had already tried everything else. My parents weren't happy about me moving schools for some weird reason but the school wasn't keen on moving me up because it was supposed to be one of those progressive, egalitarian institutions that had moved away from the 'English public school' way of doing things. In the end they agreed to get the county psychologist on the case and she came in and 'tested' me. Well, she was duly impressed and I did move up, but I remember thinking all through the test that it was pretty meaningless and wondering how it could be considered 'scientific'.
