A bit off the main topic, but I see no reason why these tests would ever be closed book. Its not like you get to read it once then never look at it again. If you can remember how to grid up, everything else you can go read it when you have a question.

Or you can be like a lot of us and you're not fast enough to ever be the lead car so you just follow the guy in front of you. (yeah that's my excuse)
