I'm thinking that if you cannot get in to an accelerated nursing bachelors program, you should consider getting into a traditional program. Yes, that would take 2 years, rather than one, but he would also be in nursing school rather than still attempting to apply. I also have a bachelors degree, I am in an Associates degree program, and if I want to go to the RN – BSN program, I can. After I'm done. In my case, since I have a bachelors degree already, I would have to take only the program coursework to get a BSN, or I could take the coursework necessary to qualify me for MSN program and skip the bachelors altogether. The 3rd possible plan would be for me to apply to the MSN program after taking the class work I need to qualify for it, and while waiting for approval or the program to start, take the other 2 courses for the BSN, then I would have the BSN, get certified as a PHN, and go into the MSN program with that, even though I was accepted into the program without the BSN.
Look at all of your options. That includes even the traditional ADN programs and BSN programs. The only downside of doing ADN program is that financial aid will be limited because you already have an advanced degree, and you would be going for a degree that is not so advanced as the bachelors you already have. I bumped up against that problem myself.
Good luck to you, I hope you find a program to get into that you enjoy!
