I obtained my Associate's Degree using the traditional method of going into school and attending clinical with my peers from the didactic courses. I graduated in 2011 and I remember it was hard work and a lot of dedication, especially with time. I did obtain my Bachelor's and Master's degree online. The best advice I can tell you, from my current memory when getting my Master's, is to work on a little bit at least four times a week. You will need to set time aside to get your assignments completed. For me, I would start schoolwork at 4p and might stop at 8p. If you're doing that 4-5x/week, then you should have no problem getting work finished and working ahead. The worst part for me was arranging my schedule or forcing in my practicum rotations during my Master's program. I had to have family take my son for a while while I was in practicum, five months, so that I could finish my program.
Take each assignment one by one. Break the whole assignment up and go piece by piece on the rubric. Turn it into a checklist. Ensure you are meeting the course objectives. I know its not easy. I feel as if I was borderline through my Associate's program, but by the time I finished my Master's programs my grades averaged around 95%.
You know, life is about chances. You'll never know unless you push through and find out. Sorry I couldn't offer any better advice, but my own experiences in education.
Hope this helps, even a little!
