I don't know if this has been discussed before but if you are given gridded laminated sheets as your scratch paper used this to your advantage. Outline a 4x4 block and put a dot where the first hole(s) are on the image. I found it very easy to unfold each fold one at a time and put dots where they should be. It was very methodical and helped me keep the positions of the dots straight. Maybe this is obvious to most, but I didn't think to do it until I was driving to the test center.
