Hi again!
The specific program that I was thinking of that lets you in with "just" an associate's is the program at Frontier, but I'm sure there are others. This program actually does NOT award you a bachelor's degree, and that's why there are only a "few" classes (seven, which is more than a few I guess

total of twenty credits) in the bridge program, which takes about a year. (and during the last term of that year, you're already starting on the master's coursework.)
Every school requires a certain GPA, but the actual number varies from school to school. Some require a GRE, others don't under some circumstances. Some require X amount of years of nursing experience, others don't. It's a good idea to hunt around and look at schools that you might be interested in, because it really can vary widely.
Good luck!
