Before taking an exam
You can do this visualization the day before and again on the morning of your exam, but it can also be a good idea to take 2-3 minutes when you are actually sitting in the examination room, after you have looked at the questions on the paper but before you start to write. This will help you to clear your mind enough to be able to access the information that you have stored in your memory.
First, take three long, slow, deep breaths. This will help you to relax and will settle any feelings of nervousness that you might have, which can block your thinking. Next, just close your eyes and concentrate on looking at the blackness behind your eyelids. Sometimes you might see imprinted colors or images - if you do, just observe them and let them fade away. Imagine that you are a very tiny person and that you are walking inside your own brain. Picture yourself going to the section where the knowledge that you need for your exam is stored. Imagine that this is stored in cupboards and that you are unlocking the doors and opening them so the knowledge can be released. The knowledge you need is neatly arranged in a row, in the correct order that you will need it. Any superfluous knowledge that is not relevant is stacked to the side on the shelves. You are the one in control. When you give the signal, the knowledge will jump down from the shelf and move out, ready for you to use it. Repeat to yourself, “I have the wisdom and the common sense to use this knowledge in the most appropriate way to answer the questions”. Take three more deep breaths, and begin writing.
