Honestly I find Economics extremely interesting, and I do like how its pretty much relevant to everything. You'll learn about how markets work, inflation, exchange rates, government policy etc. However it is a pretty hard subject for me, you have to go into a lot of depth and detail especially because of the new exams which my teacher told are far harder than years before.
For the exams, its mixed with some multiple choice for AQA, Edexcel and OCR, as well as essay questions where you have to comment on Government policies, draw diagrams etc.
However if you want to do a business course, picking business will obviously be better as well as it being simpler (or so I hear).
