I have started a degree program online at American Public University. I first heard about APU when my then-husband was in the Army, and we talked about taking classes at AMU--American Military University.
There seems to be a lot of discussion about on-line learning lately. I was skeptical, myself.
A couple of years ago I took a few classes at Phoenix for an add-on to my teaching credential, and it was academically vigorous in the extreme! I worked very hard for my grades, and learned a great deal.
I like APU a lot as well, and plan to continue for my Master's. I was uncomfortable being "just" a Civil War buff. Now I can be an educated Civil War buff!
