No, I don't think I would. The closest dental school I would seriously consider going to is an hour away (with no traffic). Even if I had stellar grades/DAT scores, there is obviously no guarantee that I would get in there. I could end up having to go to a school farther away. Plus, I already commute 30 minutes to my school now five days a week and it's already a pain.
Living near the school does come with some major benefits. Most of your classmates probably live near the school, which means that you can participate in study groups without the hassle of commuting really far. You can also be active when it comes to school events, and if you need to go back up to the school to finish projects or work in the school library, it's a none issue. Gas costs would be relatively low. Little things like that.
I'm living at home during undergrad, so I've already saved a ton of money compared to the students that I know that live on their own or on campus. Plus, I went to a cheap state school, so my cost of attendance right now (considering scholarships/grants and my own income from working part-time) is pretty low. I have to agree with Jstar, I think dental school would be the perfect opportunity for me to actually get some "real world experience" living on my own. It's a scary prospect, but at some point you're going to have to cut the ties.
Saving money is a great idea, and obviously important. But I think I'll just go to the school that's the best fit for me, has the least amount of cost for tuition and cost of living, and just do things that way. Granted, if my parents lived five minutes away from the school, I'd seriously reconsider my position. 😀
