S6 option help

I’m currently an S5 pupil doing higher RMPS, English, Mods, history and photography. I’m interested in doing politics and philosophy at uni and I’m a bit stuck on what to take. I was thinking advanced mods and English and then I can’t decide between higher psychology, politics or higher apps for my other 2 highers. I did N5 apps in S4 but achieved a D grade as maths definitely isn’t my strong suit but I was thinking that I would find apps slightly better as it’s only one paper and I would have an assignment to fall back on. Maths isn’t required for any of the courses but I’m extremely worried that if I don’t do maths again universities won’t be happy with my grade achieved at N5. I was also thinking of doing higher psychology as I haven’t done a science from N5 or higher and feel like it would be more easier to crash higher psychology rather than crash a science as I’m way better at my humanities and social sciences.
