Jacobim,
I've never regretted my decision to attend UofA. I really liked UofA when I interviewed, had I not liked it I probably would not be here right now. I liked the facilities (comparable to higher ranked schools) and my impression at the time was that the faculty, staff, and students were very friendly (which they are). As far as education goes, I think the education I'm receiving is a good one and I'll be well prepared for the clinical years and residency. I'm saving $10-$15k in tuition per year as well, so that also makes it very attractive. After taking into consideration outside factors like family, spouse and location, UofA was just the best choice for me. Good students match into good residencies, regardless of what med school they come from, and students at UofA match pretty well, so feel confident that with hard work you can get the residency of your choice coming from UofA. The schools job is to prepare you, and I think UofA does a good job of that. If you want to be intense, go ahead, you can definitely find other students in class with a similar style. However, being intense gets old quickly, you'll get burned out and then you'll learn how to balance your life a little better (not true for all, but most). The classmates who don't want to be as intense won't hold you back, don't worry about that. You can learn as much as you want and spend as much time as you want studying and probably find someone else who wants to do the same. Your classmates will play a large role in the environment around you, so you need the really serious people and those who are more laid back to balance things out. I think it's better this way, it keeps med school manageable and fun. We all get more intense around test time, so distinguish between being intense during tests and being intense all the time. There is a huge difference and make sure you know which one you want.
i hope i answered your questions, sorry I couldn't be more efficient. let me know of any other questions
good luck
ps - as far as I know, acceptance letters won't go out until the end of january
