A huge factor in the time you can spend away from schoolwork is the school you attend. Some schools are more family friendly than others - and I think it is hard to understnd the huge difference something like that can make until you see it first hand. It extends into the 3rd and 4th year too. You can pm me if you want more details on what I am talking about - but it is a great question to ask the students at whatever medical school you interview at.
