My experience at Glendale Community College was that there was a real bimodal distribution of student, with one peak around very serious, hard working students trying to better their position and another around a group of students that were just going through the motions. GCC and most CCs are already pretty cheap. By removing the already low cost, I fear that proportion of less serious students would skyrocket. (As a service approaches zero cost, the percent of user that abuse that service reaches it's maximum.)
