An excellent approach to using photoreading during a test was posted by Dana from Paul
http://www.learningstrategies.com/forum/ubb/Forum8/HTML/000707.html I have used a similar technique for tests some years ago and it works well (without the photoreading part). On the questions where I was really stumped on I called up an image of my lecturer in my minds eye and asked him to answer the question for me, just wrote down what came to mind. Did well on that exam
