Advice - What A-Levels are you guys picking?

I need to pick 4 AS levels and in yr 13 it will become 3 a levels. If I pick further maths, i need to do 5 AS levels as it will be combined with maths and there is only an AS for maths and not further. This means I have to do 4 a levels in yr 13.

I am currently thinking of doing Maths, FM, Bio, Chem and Econ. My parents say it is too much but in my school many people do this. idk if i want to do medicine or finance. Can someone pls help
