as an ivy mba, I'd advise yall to start prepping ur livers nao in anticipation of upcoming "networking events."
but seriously, it depends on the schools and their focus. are they more quant heavy? management? strictly case method? beefing up ur excel skillz won't hurt and will put you towards the middle of the pack.
I'd imagine u guys will get stigmatized and shoehorned into biotech/medical type stuff/projects- r u okay with that? honestly getting into VC/PE stuff down the road is where the beaucoup bucks lie so maybe you should try to resist being pigeonholed.... if you get a mandatory internship gun to do it at mckinsey, goldman, on a buy side/sell side/trading floor of a big bank, ratings agency, foreign market trading, etc. Something different... don't just be the "health care guy" because then that is the only type of stuff they will ever think of you for.
I'm happy to answer specific questions. But honestly a lot of the classes and material will be pretty fun, easy and straightforward. Way more group work than in typical science classes or I'd imagine in med school.
