New to this - Double Major in Comp Sci and Econ from Trinity College looking for advice

Rising college junior looking for some advice on how to enter the IB/WM/M&A field. Trinity - my college - is notorious for sending people to Wall Street, but I haven't had very much luck with internships so far. Currently I am working as a IT Intern for a software company outside of Boston, but know that next summer's internship is the most important for securing a good job right after college. I've attached my resume for you guys to take a look. Currently it looks as if I will be able to get a BS in both computer science and econ, and I would like to be able to leverage both majors during my career.

My schedule for the Fall is as follows: -Special Topics: Mobile Computing -Macroeconomic Theory (took micro last spring) -Econometrics with Lab -Virtual Communities -Independent Study in Algo Trading/Machine learning with Quantopian and Python

I plan to go abroad to London in the spring (University of Westminter, Kings, or UCL), possibly try to get a banking internship during my semester there. Ideally it would transfer over to the summer and I could continue with the internship.

Any advice for a total newbie?
