I also took Bio 1 and 2 at Phoenix College ONLINE and received A's. I like that format much better than Rio. FYI a real good tip is to find audio recordings of Anatomy lectures online. You can download and listen to them on your mp3. I listened to them in my car on my 45 minute commute to work.
A lot of people will tell you how they think online courses do not teach you as much as in person classes, especially for lab work. But, I study really well on my own. (Some programs may not accept online anatomy labs...but ASU does and, of course, Maricopa does as well...not sure about the other schools
...so be sure to check that out if you plan to apply to a different program...especially out of state programs.) The audio lectures were very helpful to bring the class feeling into an online program.
I was able to download the classes from a different professor's website at Phoenix College. I was hoping to take his course, but he ended up not teaching online that semester. I know Berkeley has online audios you can download as well. Don't worry that the audios are not from your professor. The idea here is to learn the concepts and by hearing it as well as reading it, I think you grasp it faster and better.
