straight econ only get one option in 2nd for many this is PoF.
For 3rd year you can either take the "essay" route and choose modules like econ pol in the uk, econ systems since 1918 and other stuff like that. Basically applying the macro you learnt.
Or, you can take things like Econometrics 2 and Topics in Economic theory and International Economics, which is basically more macro, micro, and maths. Joy!
Finally, do a little bit of everything and throw in a bit of business school to dilute things.
