In graduate school you are given the course objectives but not usually the resources to find them. Plan to spend about 2 hours per day for each class you take studying. A majority of the time spent will be researching topics, finding supportive literature, and assimilating all of that information. If you are disciplined about your time during the week you may find you have extra time on the weekends. I got high grades in my BSN courses but did not commit a lot of time to studying. That's not an option in NP school. I estimate that each of my papers took about 40 hours of learning the information, finding supportive research, and writing the paper. I don't regret doing it at all. Just be aware that it will take a considerable amount of dedication. Some find the online approach too isolating. It all depends on your style. Good luck!
