The first step in writing any speech is to understand the assignment.
Before you begin writing, make sure you ask your instructor about any questions you have.
Some details that are important to know:
What kind of speech are you being asked to write?
How long does the speech have to be?
How many sources do you need?
What kinds of sources are allowed (e.g. books, articles, Websites)?
What type of citation format does the professor prefer?
Create a daily and weekly timetable based on the due dates and how long it will take you to complete each task.
