When you review your report after you have prepared a written copy you should NOT memorize the presentation word for word.
It is recommended that you proofread your piece of writing in order to ensure that the organization is logical. It is also suggested that you check if your statements are supported with facts, examples or illustrations and that the language is clear and precise. You should also make sure that your thesis and conclusion are strong.
However, it is not necessary to memorize the text you produced. So, the fourth option (<em>Memorize the presentation word for word</em>) is what you should NOT do.
