LBS MAM networking

Hi all, looking to make the most out of my year at LBS. Want to break into MC, but also looking to keep my options open. Any resources I can leverage to increase my chances and make the most of my time there? Can provide more if needed! 

non-target, non-trad undergrad (but econ), data analyst internship. 

I'm also stuck on the process of messaging alumni and relevant contacts for networking...like do I just 'get to know them'? Is it possible to pursue IB at the same time? Unsure of the load this will be and if it is acceptable considering the application window. 

TIA
