While you may not have to show up to pass some classes at traditional universities, you still have to wait a semester to pass them. Under the WGU system you can simply pass the class whenever you feel ready and move on to other subjects.
Sure it does. It shows you've met a bar of learning.
There are many more considerably more transformative experiences than hanging out with a bunch of same aged young adults having lots of sex, parties, and experiences with new subjects.
You're not going to GW for the first two, and honestly, if you have valid knowledge about the degree, why shouldn't you be able to get it accredited somehow? Why must you use years of real life to sit in classrooms with protoadults who don't work?
