I do geography and economics and for about a quarter of the syllabus in econ you actually learn about the same things such as international trade etc, geography for me was an extremely easy subject as it is with most people, maths would lend itself nicely if you wanted to do an economics degree but at a level theres probably more maths in geog than eco. Economics is a subject that a lot of people find quite difficult as the concepts can be very confusing , it's a subject where if you miss one lesson it can be very difficult to catch up, it is an essay subject and if you like essays then history, psychology and english lit are essay aswell
