The last slide you speak to should not be the last slide in your presentation file. You should have three identical copies of your last speaking slide so that if you accidentally advance one too many times at the end of your presentation, your audience never knows because you don’t drop into the program, the slide looks like it has not changed. After these slides, you should include some slides that answer questions that you expect to be asked. These slides will be useful during Q&A sessions after the presentation. The final slide should be a blank slide so that if you go through all the other slides, you have a final backup from dropping into the program.
