How to protect a presentation
Build your speech on the arguments, but not on the slides. Even if your presentation is well-composed, that is, the visual elements combine well with the text, it is still not necessary to your defense strictly on the text of the presentation. You must accompany presentation own arguments, theses and conclusions, which are consistent with the content of the work. Never say "go to page 7", use this instead: "This problem has been solved on page 7".
Get ready for the performance. It is important that your speech was rehearse a few times, and chronometrical. It is not necessary to prepare the last night, the audience can easily notice it, because not everyone will be able to compensate for the lack of preparedness of sincerity and excellent improvisation.
Do not forget that the audience is real people. Over time, which are designed for presentation, the presenter must make the audience believe him. If you are not able to please the audience, all the time spent was spent in vain.
Even if you are not sure about what is said never show this to the audience during the defense presentation. Your voice needs to be convinced that you do.
No one is safe from surprises. Carefully check the laptop, the battery performance of the projector. The better you are prepared to come to a meeting and to properly prepare.
