How to create a " cheat sheet " (allowed reference sheet )
Revise all the topics to be covered in the exam/test.
Don't try to rely completely on " cheat sheets " as they will hinder you from actually remembering anything. Instead, revise everything first, as if you couldn't use a cheat sheet.
Identify key things to put into cheat sheets. Some of these are: equations, diagrams, definitions, conversions, concepts and other hard-to-memorise facts.
