The University of Phoenix is okay, but I have heard it is not as "supportive"/social as some others. Ideally you probably want to find a school with classes like this forum is where people participate and are friendly etc. Classes where people truly interact are much easier to enjoy and learn from than ones where you are left too much on your own.

If I were you, I'd take a basic online class from your local community college or state colllege/university and see if you like online studies and do okay, etc.; a class from a "real" school near you will usually transfer elsewhere and/or you could toy with the idea of taking some courses online and some in person, etc.
