University of Idaho - Independent Study - experiences please

[GMT]

It's been a while ago, but I signed up for Ethics and dropped it. My experience is limited to that 1 class (2008 maybe?) but it was 100% run by a TA who ticked me off from the word go, if there was a professor I didn't communicate with him/her. It didn't help that I had to buy their own publications of readings for the class (I hate that- really? We need to kill a tree? Does no one have a link?) and couldn't return them. I know, probably not helpful, but there are likely a few others here with better experiences.

Thank you for your reply, the TA and buying their own publications is interesting
