I took both Bio 201 & 202 online at Rio. You pretty well get out of online courses what you put into them. I tend to really dig and not slide by, so I get a lot out of my courses. I just took potluck with instructors and they were fine. The biggest piece of advice I can give regarding courses (whether on- or offline) is KNOW EVERYTHING and be able to relate everything. It does take extra effort to know the material to that degree, but it definitely pays off; particularly, when you start seeing NCLEX type test questions in nursing school. Also, Rio tends to be more work than some of the other MCCCD schools, BUT it is well worth it when you get into the nursing classes. You'll be very happy to know all those essays, for example, really DO make the nursing courses much easier. The upshot is: make sure you really put the time & effort into Bio 201 and 202 - it will pay off big time. In addition, if you find yourself on a waiting list with some extra time on your hands, it's well worth it to take Human Pathophysiology (HCR 240). It's a great course and it will really help as you get further into the nursing courses.
Best of Luck!!
