College

Never having gone to college, or even thought about it I know nothing about how degrees work, and th progressive stages. Any info?
I've been thinking about going to nursing school at UT here in Austin and I'm not sure if to be a nurse you have to actually go to college and do that whole thing or if you just go to nursing school. Searchs are coming up blank. Any idea?

Edit:

well i found a nurse forum, ha, and it seems you do have to go to college and get a bachelors(?) before you can do the stuff to become a registered nurse. hmmmmm college.....
