I just found out I have to spend another $65 on testing supplies for my class that I am already spending $400 on. And she let us know that she or the bookstore screwed up because only three of the books were supposed to be listed as required. Too bad I had already ordered all five of them and can't just return them as I bought them on line. I hate that professors don't make sure that these things are accurate. Instead we get screwed when there is a mistake.
