I think on-line education is the best way to get a degree if you're busy. I am currently studying for a masters in IT with the University of Liverpool and I find it amazing (www.ohecampus.com). Unlike what many think, studying on-line is very social, and interactive. But online university is a great opportunity for some people.
Readers should take threads like this with a (very large) pinch of salt. They are invariably asked and answered by the same person/people in order to promote their own (generally dubious) websites .
I have just finished an online master degree. It wasn't easy. In fact it was quite hard to work full time (in special education) and study at the same time. The challenges are so many, but if one wants, one does it!!!!
