The AP requirement is not just a matter of ticking a box: it is preparation for the course you are applying to study. Having a 4 in something related to the subject you are applying to study is a red flag to Oxbridge. You may not see physics or chemistry as related to psych, but the UK unis obviously do, as pretty much all of them mention wanting at least one of math/bio/chem/physics . Psych in the UK is more science (v. social science)-oriented (and more research and data analysis focused) than you might be thinking.
This! so, aside from psych you are “actually interested in”… spanish, english, gov, econ and/or stats? In which case, why are you applying to study psych in the UK?
@llamamama1714, I think people are trying to point the OP towards places like Edi and Durham (@MYOS1634) and StA’s (me, noting that it the UK school most likely to be impressed by a high GPA).
