I dont know what to think about this place, being a Professor myself, there is a scam element to this place. Getting a book publisher to produce a «custom» book for the Calhoun course, but removing chapters, printing it on lower quality paper, and actually charging more for it! I think there must be a huge cut going to the college. The«custom» book is $ 70, yet, the original can be bought for $ 35. Hmmmmmmm. Shafting the students a little.
