I got my degree through on line work. I spent about 30 hours a week studying, doing problems for turn in, collaborating via skype or online meeting rooms (with video, sometimes with the prof present) etc. Every three weeks I had a proctored exam at the local university where I had to show ID, turn in my phone, and sit under the watchful eye of an acceptable proctor while I took the exam that was sent directly to the proctor from my school, and turned into the proctor for returning to the school with a copy of my ID.
I can tell some anecdotes too. My sister is a Nursing Director at a large hospital system. There is a huge business for test takers for nurses and Dr’s - the test taker gets a fake ID with the name of the person they are taking the test for, gets a couple thousand dollars, and takes the test. Voila - instant DR or Nurse without having to learn a thing.
If someone is going to cheat, they will do so online or on campus. A cheater is a cheater.
Hell yes......and there's even an entire hit TV series where the lead character is based on this VERY idea (Suits).
