Ahhh same but hey Im waiting till November time
That's a good set of A levels though why do you want to do a fifth for it will be more workload although if you want then yeah sure go ahead
Umm I think Government and Politics would be better because Critical thinking is seen as a mickey mouse subject
and G&P would be good for the finance field as you understand the rules etc.
As for other good AS levels Im not so sure but maybe you could do a essay-based As level to make yourself more in the advantage when applying for uni's
Hope I helped
