The document outlines 10 common mistakes made in PowerPoint presentations: 1) Having poor knowledge of the topic and reading slides word-for-word. Presenters should be confident and use cue cards. 2) Using the wrong fonts that are too small, italicized, or dark text on dark backgrounds which reduces visibility. 3) Choosing poor background colors that make text difficult to read. 4) Selecting text colors with low contrast that are difficult to read. 5) Using text that is too small, under 24 point font size. 6) Including too many bullet points or ones that are too long, over 6 lines. 7) Having spelling and grammar errors without properly editing
