I am not sure that they do a credit check. But you could ask. I have not heard of that, however.
High school transcript aside, usually most programs will have you take something called a "Teas" test. It is a general education exam. You have to pass each subject by a certain level of points to pass it. Sometimes, I have heard it is the overall score. But again, I would ask.
I would look at bridge programs available in your area. If there is not an option, I would weigh the pros and cons of just doing your ADN and then working on your ADN to BSN. BUT, see about waiting lists--because many schools
If you are moving to CT, I would also see about an LPN program there, then I do believe that they still have hospital diploma RN programs (LPN-RN) in CT. Once you get your RN, then you can bridge to BSN. I would research that option.
Best of luck in your endevours!
