> every exam was take home
When I was at MIT, most exams were in-class, but open book, open notes, open whatever you wanted to bring with you. And of course that just meant the exams were much harder, because they could assume you had all the necessary reference materials at hand and didn't have to conjure things up from memory. "Cheating" was pointless, because everyone else in the room was struggling just as hard as you were.

That reminds me of what an instructor (one of the best ones I've had) said a long time ago in response to one of my classmates asking if the exam could be open-book: "I could make it so, but it's not going to get any easier." The same instructor also responded to another question with "it doesn't mean I won't change the length of the exam."
The advantage(?) of take-home exams à la Caltech is that they can be open everything and 3–5 hours long :-P (For what it's worth, being able to listen to music during an exam, ctrl+F a digital textbook, etc. was super awesome; it would deeply sadden me if that becomes infeasible in the future once enough students stop caring about the Honor Code....)
