Many ADN-BSN online programs tried to deceive students into believing that they can get their BSN from ADN in 13 months or less. That's a lie and false advertisement. They are not telling the whole story.
For example, University of Texas at Arlington advertises this past spring that you can get your degree from ADN to BSN in 13 months. After you enrolled and pay their high tuition rates, they want you to take from them American History I and II, Texas history, and other courses that have nothing to do with Nursing. You can take these same courses from Community Colleges in California at 1/6 their cost, but if you do they may or may not accept them for credit. For example, I have a friend who took US History from a community college. UTA does not accept them for transfer credit. Their Academic Advisors are trained to do what is good for business, and not what is good for you, the student. Be careful and do not fall for their traps! They want you to stay longer in their school, and pay for their courses that nobody wants to take, such as political science, and so forth
I heard that Excelsior College gives you 35 BSN credits for your NCLEX. They don't give you the run around treatment. They are located in Albany, New York. Their tuition is a little higher, but you can graduate sooner with no hassle and stumbling blocks.
