Will my offer of admission be rescinded?

Hi guys I need advice,

So I got accepted a few weeks ago into Boston University as a transfer into the school of communications, but I’m now really struggling in a statistics class and am possibly going to drop it and get a W. I’ve called admissions and they aren’t able to give me a definite answer on what to do. If I don’t drop it I’m most likely going to fail the class. Should I drop the class and get a W or risk everything and try and get a C? The last thing on earth that I would want is for them to revoke my admission into BU. Would they do that if I got a W before transferring?
