Research and BU

So BU is a huge research school, I get it. But is it unheard of for someone with minimal research to be accepted? I regrew a bunch of yeast for a semester and made a few western blots the following semester. So really, nothing.

Any suggestions on how to go about getting more experience with research as a non-trad? The kind of research that BU is looking for?

I fully understand that BU is a BIG reach for me, but having one long shot on the list can't hurt.
