Coming from an undergrad program quite a bit smaller than QMED (my future family <3 ) I will say that there are many positives and downsides to a small class. You get to know everyone really well, which can mean personalities clash, but can also mean you get to know profs really well and develop some deep relationships. I personally think all class sizes have advantages and disadvantages and it depends on the type of learner/socializer you are.
P.S. Congrats to all those who got acceptances today, and also those who didn't. Applying is a huge hurdle and something to be proud of either way
