Open Book Exams/Using Notes

[artalot]

I saw course averages go down when I allowed completely open note and open book exams. Some students just weren't studying and you can't look up all of the answers in 50 minutes. I allow a note card now, it's a good way of getting them to study. Many don't actually use the card; they just like to have it.

That's weird.  They thought that "open book exam" meant you didn't need to study at all?
