Using the PowerPoint presentation review feature can help you prepare and get feedback from others on your slides before you present.
Before showing your PowerPoint presentation, you might decide to ask someone to look over it. The two of you might even collaborate on a presentation. If you were revising a hard copy of a report, you might add comments in the margins or compare your rough and final drafts side by side. You can also do these things in PowerPoint using the Comments and Compare features.
In this lesson, you will learn how to add comments and compare two versions of a presentation.
