I don't know what to pick for my A-levels and its kind of stressing me out, what do I do?
i would just say pick what u enjoy the most honestly and if u like them all then maybe whichever ones get u better grades. if ur planning on going to university u can have a look at the ucas website and see what sort of a levels they like - there are some that unis don't like especially if you're taking another that's very similar to it
otherwise just choose what u want to study and what u like (taking in the consequences etc as well)
if u're still really confused, i would say talking to a teacher (or multiple subject teachers perhaps) really helps as they can guide you through and offer you advice from a lot of experience in their pasts
