I'm not in Idaho but I'm FROM Idaho, and miss it very much...
I graduated from EC a few years ago and had some of the same concerns it seems you have. One of the things that helped me is that I did have deadlines--I scheduled the tests before I was actually ready for them. I gave myself however much time I thought I would need, but I went ahead and set the date. That way I knew that I had a deadline to meet and it made it a lot easier to motivate myself to hit the books. Then I studied everything--and I do mean everything--in the syllabus/course outline. It made it hard, but when I finished I really felt as if I knew my stuff. My experience since then in nursing practice has borne that out. EC can be a very good program for someone who's motivated.
Hope this helps! Study hard and good luck!
