I think text books are the most expensive part of going back to school.
I was fortunate that when I went to nursing that my SIL had some older books that I could use, and I saw a notice on the boards at the school for some books from someone who graduated 6 years prior. And some of the teachers had older editions of some others too that I was able to grab. The only books I bought new were the ones for my A&P and Psychology. All the others were up to 6 or 7 years old. The pages for the information wan't the same, but the content was. But that's what books have indexs for
When I was going to buy my A&P book I saw some students in the book store spending $700 on just one book! They must have been med students. One person's bill came to over $3,000.00!!! I felt lucky that mine was only $100.00!
