Is this a good A level combination?

If you enjoy business I think it's good. What's your reason for choosing business specifically? Have you considered a subject like maths instead?

I’ve considered maths and get good grades in it ,however do not enjoy it or have an interest in it and therefore I feel I could struggle at a level. As for business- I have not done this at gcse- but I think it could be more beneficial the things you learn in future so I may have more of an interest in it.

Your subject combination should be good for both psychology and marketing. Most psychology courses need two science subjects (this includes bio,chem,physics,maths,psych) so I'd say go for it, and if you don't like business you can likely change it within the first few weeks of study!
