Once I have written my first draft, I practice my presentation to time. I usually start this part of the process around two days before I am due to present. For me, practice is very important. It reveals repetition, grammatical errors, and misplaced sentences and paragraphs. Practising also allows me to appreciate how long it will take to make the presentation and whether I will be able to finish within time.
During this process, I cull approximately 40-50% of my content and make countless changes to the order of delivery. It can take numerous rehearsals to reach a final draft. The more times I practice, the better the presentation.
