I signed up when Mark Levin was promoting this months ago. I never got any email response. Yes it is possible that I mistyped my email address but I am usually very careful about that.
I just registered again and once again I did not make a contribution for the course. I got an email response this time ("Thank you for registering for Constitution 101! This program will begin on February 20, 2012.") -- the last time I did not but I did recently get a first ever email from Hillsdale asking me to purchase The U.S. Constitution: A Reader
The Reader is $30...no indication you must purchase it, however.
The previous series is here: http://constitution.hillsdale.edu/page.aspx?pid=826
“Introduction to the Constitution” videos, with links to pdf study guides.
The class is free but they do ask for a donation if you are able. They don’t take federal money and are supported by their student tuition and donations.
Glad you are registered now! See ya in class. ;)
