Good notes should have a clear organizational pattern.When you take notes,you should write them down with your own words, and the ideas in your notes should relate to one another.That is to say,your notes should be arranged into an appropriate form for example a list,a diagram,a table,etc.
Good notes need to indicate the source where the information comes from.You need to write down the name of the author,the date of the publication,the title of the book or journal,the name of the publisher,the volume number in case of an article, and the page number(s),etc.exactly as they are written.
