may not be telling you the right information. It depends how much education you desire for Nursing.
There is the ADN which is an Associates Degree in Nursing, this requires you to complete your GE courses, as well as the major sciences: Microbiology, Chemistry, Anatomy, and Physiology. And also note this requires: a good GPA like 3.5.
For a BSN which is a Bachelors, you need the courses listed above just for the Nursing program, unless you are already attending at the University-level, you don't need GE courses since they should be completed within the first 2 years. And this is a 3 year program for the BSN.
As far as online education, I do not recommend it at ALL! it is very stressful, for nursing, it should be impossible, because it is all hands-on! Hope this helps! And good luck with pursuing your RN!
