Whyyy do classes make you buy always the newest editions of textbooks even the year they come out, and with your own money? ( already paying tens of thousands come on
the changes between editions are minimal, and most of the changes are in page numbers and problem sets
most of my professors say that they didn't choose the textbook and so department/administration would be responsible for textbook choice.
should we have to pay $60 extra for a different set of problems and tiny changes?
there's no other explanation... colleges are in business with the publishers
