For my Alevels i picked psychology, economics and business (looking to drop business to do either maths or english language). I need maths for majority of the unis in the uk to do a finance related degree. I got a grade 5 at gcse due to not bothering to revise. I could have gotten a high 7 low 8 with it but due to how my school works they require a 6 to even take the course. Is there anything i can do extra curricularly in order to get into a good uni in replacement of an a level in maths?
