A level optionsWatch
1) Maths, Further maths, Economics, Geography
2) Maths, Further maths, Economics, Physics
I imagine human geography has more links to economics than any aspect of physics (so you might find it more helpful/interesting) but I can't see that taking either would disadvantage you, both combinations are brilliant.
Both are good combinations for an Economics/Finance degree; however, getting into uni is like a game. Compare physics & geo - at A Level, physics is really difficult.. so if you like Geo & Physics equally as much, then I suggest picking geo. Should be a lot easier for you to get a good grade in hence higher chance of getting into a top uni as I know many friends who have to put so much time and effort into surviving physics (and getting a B at least) that their other subjects suffer. If you're indifferent about them both, choose the easier one
