Free textbooks are just as effective as costly ones | Buy Cheap Used College Textbooks

"In a result that will make college students rejoice, a group of researchers at Brigham Young University have found that a free textbook is just as effective as an expensive one.

BYU’s Open Education Group studies open educational resources, free and open-access educational resources they’ve found that can teach students just as well as paid resources.

The group’s research not only showed that students using the free materials do just as well, and in some cases better, than if they were using a pricey textbook, but that the students were also more likely to stick in a course and not drop out."
