iirc open-book means that you can use the lesson book or something
basically meaning you don't have to memorize everything because you'll have a book about it all
So, it's not really a test if you're copying out of your book or directly from notes then.
It's just... answering questions via making more notes.
The only time I've ever done a test "open-book", was when doing some mock exam-questions with my notes for practice for an actual examination.
As TheArmyGuy said, a test that's open-book doesn't sound like it's for intelligent people at all.
It's almost as if you're not clever enough to actually properly learn something in the first place.
'Heh'*
No, he first put "haha", then changed it to 'heh', because people found 'haha' to be too offensive.
