Write down each point you wish to cover in your summary. Make each one no more than one sentence.
Arrange the points in their most logical order and place a Roman numeral next to it. For example, the first point would be "I," the second point would be "II" and so on.
List specific points that you wish to make about each topic under the main topic. Place a capital letter, beginning with "A" next to the first point, "B" next to the second and so on.
List additional points under the sub-points by denoting them with normal numbers, such as 1, 2, 3 and so forth. Any sub-points from there would be denoted with lowercase letters.
Repeat this process for each of your main points, then use that information to construct your summary paper.
