Presentation day checklist: 20 minutes before you start

The slides are done. The remaining failures are boring and preventable: the clicker is on the wrong channel, the video needs Flash, the fonts substituted, or the file is still named final_final_v7.pptx on a USB stick that the lecturer’s PC cannot read. This is the 20-minute checklist we wish every seminar used.

Files

• One master PowerPoint, one PDF export. If animations fail, you still have a readable backup.
• Put both on a USB drive and in email or a cloud folder you can open without installing an app.
• Open the file on the presentation computer, not just your laptop. Fonts and videos break on other machines.
• Turn off presenter-mode surprises: hide unused slides, delete speaker notes you would not want on a projector.

Room and hardware

• Advance every slide once with the actual clicker or keyboard.
• Check audio if you have a clip. Set the system volume before you start talking.
• Disable notifications and hide the bookmark bar.
• If you need the internet for a live demo, have a screenshot of the happy path. Networks fail during graded talks more often than in rehearsal.

Timing

Speak the first two minutes out loud in the corridor. If you cannot finish the purpose sentence without notes, simplify slide 1. Mark a “skip if late” slide in the middle — usually a long related-work slide — so you can protect results and Q&A.

A 10-minute seminar is not a 20-minute seminar spoken faster. Cut slides, do not cut pauses. Silence after a chart is when the audience actually looks at it.

If something breaks

Do not narrate the failure for a minute. Switch to the PDF, describe the missing animation in one sentence, and keep the argument moving. Examiners grade recovery more generously than a perfect theme.

If you adapted a public deck, keep the original file closed during the talk. Present from your rebuilt file so you are never scrolling through someone else’s speaker notes on a projector.

After you sit down

Write three things the questions revealed. That list is the outline of your next version. Students who do this once after every seminar improve faster than students who only restyle templates.
