Well, errr, that's gonna be a shockingly small amount of your time. At least you know you'll have fun when you can, though.
Not really. The vast majority of pre-meds don't know much about the schools they're choosing between at all. Yeah, you can get location, cost, and curriculum down without much of a problem, but the things that you'll actually be doing from day to day are shrouded in mystery. What'll your class be like? How well does the curriculum actually work? What are the professors like? Exactly how much free time will you have? How difficult is it? How's the administration? What are the attendings like? What's clinic duty like? What's your daily schedule like? The list goes on. Most people don't get useful answers to any of those questions, let alone all of them. Interview day is particularly bad to go by since it's designed to make the school look all bright and shiny and cool. Chances are they're not going to tell you about the senile professor who would've been fired years ago if he wasn't tenured or the ******* attending who'll rock you during your IM rotation.
