These hard open book test stories are great, but taken in the context of it being high school and the other suggestions ("Weigh the merit of using any essay questions at all", "Offer a maximum of 3 choices", etc), it's pretty clear that the suggestion of open book tests with page number references is not meant to ensure that teachers give tests that you can only pass if you actually understand the material--it's made so that people will do better on the tests because they'll be easier.
