It’s a scam. Everyone up and down the line gets rich off daddy’s wallet. There is no reason to require new textbooks with a CD which only allows one student to sign up on. That CD charge to submit homework should be included with tuition.
Back in the day, I bought used-used-used books for a couple dollars. Or used the library copy. Or used texts my parents still had. The only thing that had been updated from my parents’ Bio and Chem textbooks were the pictures from black and white to color. The content hadn’t been changed. Chaucer and Shakespeare haven’t updated their works.
It’s because Calculus completely changes every year! ;p
