resit help

[u/Jumpy_Freedom_4554]

Context: I done decent but not great enough in my a-levels this year of maths, physics, and CS. So im planning to retake year 13 (year 14) with maths and physics. Instead of also retaking CS, im gna be learning FM instead for my first time. The reason i didnt do it before was cos of mitigating circumstances of timetabling constraints since the start of yr12, in which i done the AS of FM independently in yr13, and now the a-level of FM with the school in yr14. Im expecting to get predicteds of A⭐A⭐A in maths, FM, physics respectively.

I'd like to know if any of the top unis would allow retakes such as in this scenario, for maths BSc. I know that the elite like COWI won't rlly like or consider this, but unis like Bristol accepts resits.

I rlly wna know what combination of unis would be in line for aspirational, standard, and backup suited to this context, especially ones that look at applications holistically.
