Health and Medicine Course

Hello, does anyone know how many total videos there are in the health and medicine course and in the NCLEX RN course? I've seen people post the number of videos included in other courses such as math, but I've never seen anyone count the videos on health and medicine nor the NCLEX RN. Someone please answer if possible. This can help me plan ahead of time to see how many videos I need to watch a day in order to finish all the videos in a certain amount of time, thanks. I also have a second question, does anyone know which course is better? Health and medicine or the NCLEX RN course which is now retired. I'm hoping to become a nurse when I'm older when I enter college soon. From what I've seen they appear to be very similar courses with most of the videos being the same, however they do not have the same number of videos and not ALL the videos are the same. Again, since I want to be an RN I want to hear second thoughts on which course is better for me.
