How to set myself apart coming from a non-target school

I'm an undergraduate sophomore majoring in finance with a minor in economics and math from a non-target school. Even though my school is a non-target, in recent years there's been an increasing number of graduates and alumni going into IB and similar careers. I'm looking for boutique internships for this summer and am involved with 3 different clubs. Is there anything I probably am not doing that I should be to set myself apart so I will be able to break into the IB world?
