i need alevel maths but i am horrible at maths

right now i am studying BTEC Level 3 National Foundation Diploma in Computing and then i will be going onto the extended diploma next year.
i am completely in love with computer science, i am by far the best in my class and are predicted D*D*D from my tutors, just off coursework, i work in computing, i have a job working with pcs and i am currently doing a cyber security cisco course. now my problem is, is that i really want to go to uni, and a good one. but most computer science courses require a-level maths. i have never ever been good at maths, i only got a 4 at GCSEs, and even with a foundation year most unis wont even accept me because of my b-tech and low GCSEs grade. should i just resit my GCSEs maths, i know i could do better as i had a lot going on at the time, but then even with a good GCSEs grade, unis want an engineering btec for the foundation year. so should i just drop out
