seriously... a smile went across my face from cheek to cheek when I seen PSU step into the digital game. Out of everyone, I think they offer the most undergrad/grad/certs out of any other university, online. The caveat to their approach, is that you may need to take a proctored exam at a branch campus, or other university/school that has certified exam proctors. Carnegie-Mellon, Stanford, and a ton of other elite schools are hopping on the ball too.

I almost came in my shorts when I seen this listing, because I work for a living and the online thing is freaking insane for me. Even tho that list may promote certain majors, those colleges are more than likely to offer a ton of other degree types, so browse through the colleges and see what's up your alley. Why anyone would look over these schools and go to No Name U, is beyond me.
therein lies the problem. While Stanford, Carnegie-Mellon, Penn State all have online degree programs, they don't just let anyone in. To get in over thousands of other applicants, is a testament to your ability on its own, and is very rewarding. To graduate is even more so. I wouldn't dare look to go to U of Phoenix or some other school with no standard, unless I had no other options.
Bottom line..if i'm going to plunk down 25...35k/yr on some grad program, it won't be at a for-profit school, that doesn't even have a physical campus or ranking against traditional schools.
