I’m taking my first class and finished the first week. We had good amount of reading, 2 chapters, outside sources, video presentation, replies to students and the quiz. Very doable if you can manage your time. Some people take 2 courses in 8 weeks, some choose one at the time.
school probably wants to see if you can handle based on your previous education. From what I see the first class is reading and application of néw information to your practice. Did u ever take any online undergrad courses?
I think if you really want to become an NP you can totally do it. If you are employed full-time , some people suggest to do a class at the time. Both manageable but u might not have a lot of time outside of school and work. It’s time and financial sacrifice to make based on your situation
