Wish I had known *that* before coming to college.

Before I came to college I wish that I known that you really don't need a book for all the classes your in. At orientation I signed up for the pre-packaged books, which was handy but a mistake all in all. I think that if I had came to school and went to classes for a week or two, I could have found out which class actually requires a book, and saved myself a couple hundred dollars.
Just today in my economics class the teacher, who said the book was great and manditory in the first week of class, has waited until past the return date to display his deep hatred for the book, writers, and anything to do with either. Fantastic.
