Which subject is better , Furthur Maths or physics

if you are intersted in the technical sid eo fmedicine better optforphysics rather math and if you are interested only in machinery stuff go for maths

Surely it would be better for you to take Biology and Chemistry than Physics or Further Maths. I don't think it really matters though, as long as you get good enough grades to get into university, so I would take the one that you are most likely to get the highest grade in. It would be wise to check with the university whether they prefer a particular subject first though as that may alter your chances of getting in.
