I am starting the ADN program this fall as well and our nursing courses are only 9 credit hours so I am taking a Sociology class to bring myself up to full time and besides it goes towards my BSN so it all works out. I think it is completely doable since you don't have a family to contend with or to take care of, just yourself.
Danilu14, I had the same situation as you and I just had to show proof that my financial situation had changed and the financial aid office based my financial aid grants on my new current financial standings. Each office has different ways of doing things but when your financial situation changes so drastically they usually base it on the new information.
