The 11+ is what students have taken since the late/early 50's...what it is is that you take your '11+', and if you pass then you can get into a grammar school, otherwise you have to go a secondary or a private school...i think that the total mark for the 11+ is 150 (not sure), i got 111, and the school that i now go to required 110 for the pass mark in 2001 when i took my 11+... SAT's are basicly tests of the three main subjects (English, Maths and Science), and it will allow ones teacher(s) to see how well you are doing in school...I think it is year 6 and 9, i think there is an exam called the KAT's in year 5... Nowadays its; Infantry, Y1, Y2, Y3, Y4, Y5, Y6, 11+ test, Y7, Y8, Y9, Y10, Y11, GCSE test, Y12, Y13, A-Level test, University/Collage/Leave school
