Hmmm I always liked open book exams. Never thought that they required a deeper understanding. They seemed to fit my way of thinking. I never had to search for information to answer the question. Merely to support what I knew or confirm an equation or graph was the same as I saw it in my head. Basically, prevented me from making a stupid mistake.OMG, where I went to school there was nothing so dreaded as an open book exam. It meant you had to know things at a much higher level.
