MWU-CPG really tries to get you started thinking about residency first quarter, for the very reason that you have a year less to think about it and no summers off to do independent internships. Nearly every faculty member is doing research in some capacity, so if you think that residency might be for you, you can find a project to do. (I'm working on that very thing right now... ha.) MWU has several residency openings it has partnered to create and is working on creating more.
That being said, I have no idea how I'm going to feel about residency when I'm closer to being done with pharma school. I do wish I had a bit more time to explore possibilities, and I feel like I'm trying to keep the door open rather than work towards a goal. That's the trade-off for going to a 3 year college, though. I don't feel like having chosen my school is going to limit me in residency opportunities, but you really do have to be on top of it.
Here's an example to illustrate the time crunch: One of the best ways to get a residency is to network with the folks at the place you want to get the residency (so I hear). We choose our APPE rotation sites in the winter quarter of 2nd year - so basically a year and a half after you start school.
