Wow, you might be my twin.. I chose Biology, Chemistry and Maths for AS, and couldn't decide between physchology and english. I would definitely describe myself as a 'science person' but I enjoyed english and was reasonably good at it. I picked english in the end and it was definitley the right choice for me. Quite a few friends did physchology and they all hated it and dropped it at the end of the year (i think 70% of people dropped physchology for A2, though this probably had quite a lot to do with the teacher). Most people in my English enjoyed it and got an A or a B at AS (I got an A, which I don't think I would have got if I chose physchology). I liked the reading and even the essay writing, wheras I've been told physchology has a lot theories and ideas but not a lot of science (which was what drew me in in the first place). I do think physchology would benefit an application to uni for science slightly more and the brain is very interesting, though english lit is a respected academic subject and essay writing is a skill admissions tutors will admire... So my recommendation would be english lit, but good luck whatever you choose
