A recent BBC article by Zoe Thomas (http://www.bbc.com/news/business-36751075) has explored whether free university tuition would work in the US. In the meanwhile bestcollegereviews.org has provided a description (summarized below) of eight US colleges where students are already attending colleges at no cost (http://www.bestcollegereviews.org/features/8-colleges-where-students-attend-for-free/ ).
8) College of the Ozarks: A Christian college in the Midwest. This College offers bachelor degree programs for different fields of study – from accounting to culinary arts. This college provides free tuition for the 1,400 students attending yearly, but students must work at least 15 hrs/wk and two 40-hour work weeks through their campus jobs.
