How to get into LSE, Oxford or Cambridge for a PhD in Econ (Development)?

<p>I'm currently a sophomore, just finished freshman year, at Occidental College in Los Angeles, and want to know what it takes to get into a PhD program at LSE, Oxford or Cambridge for Economics. For my econ major, so far I've taken
Econ 101 (A-)
Calc I (B-)
Econ 102 (A-)
I'm planning to take next year for my major
Econ 251 (Intermediate Macro)
Econ 320 (Development Economics)
Stats
Calc II
Econ 250 (Intermediate Micro)
Econ 272 (Econometrics)
I'm also planning on taking (for math)
Real Analysis
Multivariable Calc
Linear Algebra
So far my GPA is a 3.43, with a 3.0 first semester freshman year and a 3.85 second semester freshman year.
This summer I have an internship in Congress with a Congresswoman who I worked for in high school, and for next semester, I have a research assistant position with an econ professor who I was close with.
Am I on the right track? What more can I do, and what GPA, GRE scores and extra curriculars do I need to get in?
Thanks</p>

<p>Um, first you have to not only finish your undergrad, but also get your Masters. For the Masters, rumor has it that Oxford likes a GRE score of 166 or better, but that’s hear-say. You need to do some serious homework about the courses at each uni, b/c they are more different than you might realize. Their websites are clear and useful- go have a root around in them!</p>

<p>The key element is how much math you will take - it’d be best if you could double major in both math and economics. You need A’s in all your math classes, too. </p>
