Core Maths and Phsyics??

I want to do Physics at A Level to have a maths subject so is there any point in taking core maths and if I do take core maths should I take biology instead at A Level

If you want to go on and study physics at uni core maths wont' be enough - you need the full maths A level. Core maths is AS standard but studied over 2 years - it won't count as a full A level for applying to uni. So you would need to do 3 A levels + core maths, not 2 A levels + core maths. (You could possibly get onto a foundation year with 2 + core maths - you need to check uni websites)

Without saying what you want to go on and do, and your other subject(s) it's hard to make suggestions

Which core maths are you considering is it level 3 ?

Yeah it’s level 3

Its only for a year so depending on what u want to do in the future its a good idea i found core maths pretty easy its mainly statistics and basic math theres no algebra and hardly any difficult graph work so it wont really help you with physics
