I think that the case-based style of learning definitely gets easier as you have more experience with it, but whether or not that translates to greater enjoyment of the style I think probably depends on the person. By the end of block 1 I think I had the "system" figured out pretty well that it wasn't taking me as long to do what I needed to do, which was nice, but I didn't like it any more than I did on the first day. But some of my classmates started out skeptical and really liked it by the end, while others seemed pretty gung ho on PBL in the beginning and eventually became jaded. It's really a personal thing, I think. Either way, I wouldn't let it worry you too much - Mereafterthough and I are living proof that you can get through it with your sanity intact even if you don't love it, and no one (at least in our class) has dropped out because they didn't like/couldn't handle the PBL system. Who knows, it may really grow on me this spring during block 3. I'll let you know if that happens. ;-)
When I was trying to decide where to go to vet school PBL was a huge road block for me because although I was fairly certain I would be able to succeed in the system (which I have so far), I was also fairly certain that it would be a huge pain in my @$$ (which, honestly, it has been so far). In the end my decision came down to money, and even though I'm not PBL's biggest fan, no regrets here. I will reiterate that plenty of people (maybe even the majority) really really enjoy the case-based style at Cornell, and you very well may be one of those people some day! I don't want anyone reading this to be scared off, because Cornell is a great place with great professors and clinicians, even if you don't love PBL. Do feel free to continue to ask any questions you have about PBL or Cornell in general. Compared to some other schools there aren't many of us Cornell folks on SDN, and when I was in your shoes last year I really wished there were.
