I didn't have any homework in mine either. I know that we had a book, and regular quizzes (tests), but we never turned in any assignments. The work was very simple, and I had no problem
keeping up with the reading (Yes, it is common sense!) while working full-time.
I think the fact that we had a simple text made everything easier. We used "Mosby's Essentials for Nursing Assistants" and it had a lot of diagrams and pictures, and there were a lot of bulletized sidenotes... sometimes when I had a really long night at work, I would just review that, and do well. (I know I can be a SLACKER!
... but it's not rocket science... got an A!!!)
I think every program is different though. Mine was an 8hr/dy 5dys/wk for 6 weeks. Our skills labs were incorporated into class time. I know some people that did it as a 4-month program, and I think their curriculum was very different from ours. Hopefully you'll hear back from the school soon!
