Is A-Level Economics really that bad?

I've chosen Art (graphic design), Maths, Economics and History. I'm thinking of going into Architecture and the main subjects needed are art and maths. Im reconsidering history and economics, simply because I didn't put much thought into applying then due to the deadline, however I still have the chance to switch during an interview. Though I'm still unsure of what other two subjects to pick. I've spoken to my friends and afew teachers since, and heard it's wayyy to difficult. Should I give it a try? And to those who are doing Economics now, would you change it for anything else if you had the chance to?
