My Nutrition course was online and a bit more difficult then the above posters' courses. However, I did well because I worked hard and learned the information. I also had 14 weeks as oppose to 8.
By the way, I think you can do both work and take the course. I will be in summer school taking an online patho class while working 2 jobs and taking care of two kids. It is not easy, but I managed to be successful last summer and plan to be successful again. GL.
