Online universities may not be too highly thought of by future employers or graduate school admissions officers. Why have you decided not to ever go on campus? If you’re afraid of the atmosphere, you’re going to have problems wherever you go. Also, as pointed out above, you will miss meeting faculty.
I recommend that you go to a regular college, but in the night division. Evening classes are usually filled with working people who are ambitious and want to advance. Very few of them will have death’s head tattoos or pierced eyebrows. They probably also spend their spare time at home doing homework and feeding their kids, not hanging out at the nearest beer hall.
A good idea would be to check with employers in your field/area and see what their views are about online degrees. You could save yourself wasting a lot of money and time for an online degree that won’t get you what you want.
