Stressing out about choices

Im stuck between picking something im pretty sure im going to hate ( business studies) but has a nicer work load and something i enjoy (art) but has a larger work load. My other two subjects are biology and chemistry and its just really beginning to stress me out over what i should do.Any help?

Have you got any idea what you'd like to do after A Levels?

My original goal was to become a vet, however im beginning to realize that my extremely bad memory will stop be from doing this, im still going to give it my all but with my memory problem im not sure i will make it. My secondary option would probably be a game designer, i love creating characters and scenery ect and i did plan on doing commissions in my spare time when my level of art improves.

Im scared the work load will be too much for me to handle though and im getting mixed replies from people :/

Yep they allow you to change within the first few weeks of starting if you change your mind

I've chosen to do Biology, Psychology & History. Do you think these are good choices?

I hope to go on to university to possibly study Healthcare Sciences in Cardiology, although if I don't get a minimum grade B overall in GCSE maths (which will mean I can't do A-Level Biology, thus not being able to do the former) I'd like to do law or psychology.
