I'm heading over to London for LSE's general course in the fall, and I'm wondering if anyone has an idea of how useful it is in terms of Econ PHD admissions?

I plan to take some math(Real Analysis, Optimization Theory, Prob/Stats), the hard metrics course, and some other Econ/Finance type class.

Any specific extra-curricular activities worth getting into while I'm there?

How likely is it that I will be able to get a useful recommendation letter?

Thanks!
