I don't get why memorization is still so important in exams. If there are commonly available tools that allow you to get the correct answer in the allotted time, what is the problem with that? Sure, there are things you will simply have to have memorized, but if you have to take the time to look those up, you will simply run out of time in a well designed exam.
My best prof's exams were open book, open door. You could head to the library during the exam if you wanted. Of course, if you did, you would never finish the exam.
