Are there any online nursing schools?

How do you think you'll learn to draw blood, insert an IV or catheter, observe surgery or an autopsy or any of the other things student nurses do by sitting in front of a computer? Are you aware of the fact that some hospitals now require all the nurses to be RN-BSN, and the trend is expected to continue?

You can't go to nursing school online. You do however need some college before nursing school which you can do online.

Since you've already graduated college, find an Accelerated BSN program instead of doing an Associate Degree program. You might be able to take some prereqs online, if you haven't already earned them in the context of your previous Bachelor Degree, but lab sciences and nursing classes have to be taken in person.

If you are already have a BA degree, look into the ABSN degree. It will not be easy, and it may take you longer (what degree do you have?) You will have to bite the bullet and take out a loan like most students do. It is not going to be a piece of cake, but it is possible.
