i want to drop maths

i really want to drop maths. it’s not like i’m failing or anything, i got a B in my recent assessment. it’s just that im really not enjoying it and everytime i do it it just feels like a chore. for context, im studying 4 a levels, biology, chemistry, maths and spanish. i’m hoping to apply for medicine next year! yes, i know spanish isnt a science subject but im already at an A* in spanish so i really don’t want to drop it, especially since its my highest grade atm. i just feel like if i drop maths then i will have loads of free time, and my workload would be a lot lighter. the issue is that i dont know if my college would let me drop maths, as im not doing terrible in it so i dont know if they think i am justified in wanting to drop it. what should i do?
