Guy's law exams are open book, but what exactly does this mean, does it mean I can bring in textbook + written up notes, or can I go full out and print off hundreds of pages of summaries and all my prescribed reading and stick them in a folder and bring them in, then organise them so I can easily get to what I want? Surely this is preferable to written notes as computer generated notes can be easier to read over quickly and differentiate from mountains of blue pen ink.. if that is the case some people bring in massive ring folders of works??
