Graduated with a biology degree. Molecular biology, to be exact.
Went back to nursing school.
And yes, it was much easier than my biology degree was. But I do acknowledge some facts. Such as: I was an older student, so not focused on the partying aspect of life, and I'd also learned my trouble spots with school. Like I couldn't study at home, I had to study at school, in the library. I knew time management and the risks of procrastination. I was also able to skip most of the pre-reqs, because I had done them all, so until the actual nursing program started, I was able to take one pre-req a semester and fill the rest of my schedule with fun stuff. But it also applies to once the program started, when it was all nursing classes, all the time.
My professors made it easier, too, because while in biology I was expected to know everything, nursing freely admitted that no, I didn't need to be able to parrot back the book. I needed to be able to take what I was learning, combine it with my previous knowledge, and synthesize the answers based on different situations.
