I have been in the program a full year and I have had a prompt response to every email. I have had to call graduate advising more than once to get a hold of someone, but even the graduate advisor is super nice.
Yes, I feel I am learning. I do hear complaints from other students, I don't know why I haven't had any problems. Even my secure exam proctor worked as soon I plugged it in and set it up. So many other students have had nothing but problems. I have not contacted faculty for that much, I have not had a lot of questions. When I have had to contact faculty, they have all been very nice and responsive. Maybe I have just been lucky!
To be fair to those students who are having problems, it isn't the program for everyone. It is very hands-off, it is for students that are very self-directed. I think they could make that clearer before students apply. For me, that works.
I don't know if there are more unhappy vs happy students, I do know that much like most things in life, you generally hear more from people who are unhappy than from those who had no problems. So I'm not surprised the voices of unhappiness are numerous out on the web.
I don't find the material hard to learn, just time consuming.
Congrats on the new family member. :)
