Honestly recommend economics! It's not too difficult and almost impossible not to find it at all interesting even if you have no interest in it atm as means you can understand so much more when watching the news etc. Everyone at my school loves it even if they have no intention of studying it at uni and lots of people have changed plans to study it at uni when they weren't even considering it before taking it as an a-level! Good luck!
