I'm currently enrolled an accelerated nursing program where I will receive my second bachelor's degree (BSN) plus a generalized master's degree in nursing in only 18 months. This program was a better option for me because of financing. For a second bachelor's degree, you won't get much aid if any at all. This program, because it's a graduate program, opens up a whole new area of financing which I desperately needed. Plus, for just an extra 6 months, I'll receive my MSN. It's generalized, but it also shaves 6 months off if I go back to get a specialized master's degree later.
For pre-reqs we needed: A bachelor's degree in anything, A&P I and II, inorganic and organic chem, microbiology, intro to psych, stats, child development, and nutrition.
