Try buying books for a computer technology major. For one class I spent 500 dollars on books alone. What was stupid was we didn't even use 3 of those 4 books. The list said required, later on the professer said that they (the 3) were optional.

They didn't really tell me anything I didn't already know either. The first chapter of one book was "How to double click". Took 40 pages to describe that.
