What 4th subject should I take? Help!

Okay so I'm dropping chemistry, because I find it really hard already, and have already got scared of the course lol.So my options so far are maths, economics, business.I have to take 4 and I'm going to change it tomorrow.I want to go to a good uni, and I have heard that unis dont like economics and business together, so I was considering to drop business at the end of yr12, but that means I will have to carry on whatever I chose as my 4th subject.I was thinking of taking sociology, philosophy or psychology.I didnt take sociology or psychology at gcse, but I have heard that sociology is quite easy, but psychology is more interesting.Im not sure whether to drop business and carry on with whatever I choose as my 4th, or drop my 4th subject and carry on with maths, economics and business.I'm really stuck, and need to make this decision tonight.Thanks!
