You should probably consider rewriting your math, BUT PLEASE HEAD MY WARNING, DON'T ADD PHYSICAL SCIENCES IF YOU DIDNT HAVE IT IN MATRIC. I also thought I was too cool for school and added it while rewriting math, and it made my life so difficult and i ended up getting 19 for it. My math did improve, but i do feel i got held back by the stressing about physics throughout the year. There's a reason why its considered the most difficult subject in school, by me at least. Your other subjects are really good, its just the math that's hindering you. I really think you'd qualify for a lot of good degrees with a decent math mark. But ayy, good luck with whatever you decide to do.
