Community College Help?

Alright. So I'm a junior in high school and starting to think about college and what not and figuring tuition and costs. I want to become an RN and I know I could either get a BSN from a 4 year state school or an ADN from a community college and possibly transfer to get the BSN. My situation is if I go to a four year college it will cost a lot more and I don't want to constantly hound my parents for money while I'm in school. My sister goes to Emory and for the last four years all I've heard about was how much less money we have now and I definitely see it in our lives since she started going there. I want to know if I should go straight to the four year school and pay the extra money (likely a lot coming from my parents) or go to CC and try to pay for most of it myself or scholarships, then transfer if I can. I hope somebody can offer me some pros and cons to each and any advice is helpful. Thanks!
