Complete Concept Guide (100% Curriculum Coverage)
1. The Rules of Visual Hierarchy
Amateur slides are crowded with walls of tiny text that nobody reads. Professional presenters follow visual hierarchy: one bold high-contrast idea per slide, powerful supporting imagery, and minimal bullet points.
2. Custom Animation Timing
Animations must serve understanding, not distraction. Setting animations to 'After Previous' or 'With Previous' allows seamless cinematic sequences where charts reveal data points synchronized with speech.
3. Master Slides and Presenter View
Editing the Slide Master applies uniform fonts, logos, and slide numbers to all existing and future slides. Presenter View shows current slide, speaker notes, and timer on the laptop screen while the projector displays only the full slide to the audience.
