Thanks so much for sharing. It is true, while they may need to purchase and keep a few of their books for future reference. Some books they will never want to see again, LOL We over spent Freshman year, and now my Blue Jay has found ways to cut that first year cost by 1/8th at least. By selling some of her old etc. Some courses she found she didn’t need the book after all…..I do have a sort of off topic question…As you posted this, I am trying to decide on purchasing on AP World History book (new 6th edition therefore new and no used available) for my 10th grader in HS, as they only have a class set. Hate to shell out $100 bucks but it will be tough for him not to have one at home.
