I had a previous bachelor's in Accounting and went with the 2nd degree accelerated BSN at Norfolk State. I know other schools offer the same program, and I think it was a good way to go. I honestly don't know how NSU will be in the future because it was going through a reorganization period and a few of my favorite teachers left. But Old Dominion University also has a good reputation in the Norfolk area. I don't know about any other schools in the state. I did have to take quite a few prerequisites before I started to catch me up, but I took them at a local community college and saved some $$.
Anatomy and physiology was very hard.
It was a ton of memorizing, but no one failed our classes.
The math isn't too complicated. I'm good with numbers though so I'm not the best judge. There are formulas, though, and once you understand them, it is much easier. Some of it is conversion formulas like ounces to mLs and kg to pounds. Yes, you do use it in practice. Even if the pharmacy has already calculated the drip rate or dosage, you should check it yourself to prevent med errors. Also, some meds are dosed based on weight, like heparin.
It's awesome to know a foreign language and that will be utilized in your career. Good luck. I hope I helped a little.
