Alevel options help!!!!!!!!!!!!!!

I'm currently taking 4 A-levels but must drop one as I do not want to take 4. I am taking Economics,Business studies,Psychology and Drama. I need some advice on what subject I should drop. I have pros for all and very few cons. I really enjoyed business GCSE and did well (grade 8) also my class is very small with just 10 people. So, I think Business is a good option to keep as I find it easy and the small class may be helpful if I need teacher help with anything. I also did very well at drama GCSE (Grade 9) and really enjoy the subject so I don't want to drop it although it is not a very well respected a level. That leaves Econ and Psychology. I really enjoy both and am good at maths (grade 7) and Eng lit (grade 8) but I don't know what out of these 4 I should, drop please help.Ps I want to study a finance related degree at uni although still want to keep my options open as I feel I may change my mind throughout A-levels. Thanks!!!!!!
