By the way the 4 ASs we are supposed to do do not include General Studies. I suppose they would allow me do 5 if I insisted - but it's so unusual. 1 person in our L6th of over 100 is currently doing 5ASs, and all the teachers think she is mad. Our school just has a policy that they we should do 4ASs and 3A2s (though they're slightly more flexible about the number of A2s you do - I think about 5 last year did 4), and this is a school that sends quite a few to oxbridge each year. I think it's so we don't slip down the league tables with regards to percentage of A grades achieved.
The Maths and Philosophy course does look lovely, but the absence of any sort of applied maths is a reservation of mine. Also, the joint schools look harder to get into - for example, the acceptance rate for History and Economics is 15.2% (according to the Oxford prospectus) compared to the 30.2% rate of single honours History.
"they are more interested in the way you think rather than how many things you have read"
I suppose that is true, especially for Maths/Science courses, but the Cambridge prospectus for English does say 'you will have read widely, even voraciously, and well beyond your examination syllabus'. I am just worried I won't have read, and thought about in depth, enough things if I do more than the usual number of AS Levels.
