All Senior Students should be doing revision notes.
This is a simple note-making style. Your paper is first folded in half and given a title for the work you are studying. On the left hand side you write the key terms, dates, events, people, concepts. On the right hand side you write the explanations, meanings, supporting facts etc. Concentrate only on those points that will help you recall the topic content. You fold your paper in half which then allows for easier self testing.
