You are blessed that financial aid is available and granted to you. I suggest take course that interests that interests you most. My sisters took course that was chosen by my mother and grandparents that's why they were overwhelmed and were not determined to make use of their career. They were full time students but were not able to take full load because they were having hard time studying matters that are not interesting to them which made it hard for them to understand. Do you have an option to take subjects that are interesting to you? Don't think of the past failures, they could just be blessing in disguise.
