I'm not yet in nursing anesthesia school, but I've sent in a couple applications and have interview offers. I went the community college route first then completed an RN-BSN program afterwards. I'm not a traditional student, though. I already had a bachelor's degree in another subject when I decided to go into nursing, but all of the second bachelor's degree nursing programs
in my area were accelerated. That basically meant I couldn't work and go to school, and I certainly couldn't afford to do that, so I opted for community college instead.
If you have the option, I'd recommend going right to the 4-year BSN. Overall you save time, plus why work and go to school and when you don't have to? Being a new nurse is stressful enough without having to worry about your GPA and silly group projects.
