Hope this help☺️
CHOOSE YOUR TOPIC: Usually, you go to an extemp prep room where topics are posted on the wall. Bring your research materials (your “extemp tub”) to the room.
CREATE POINTS THAT SUPPORT YOUR THESIS: Take a moment and think up what would support your thesis.
Be confident - Look up, breathe deeply, say to yourself something positive – 'I'm going to be fine'.
Focus on the audience - Every presentation, including impromptu ones, need to be audience centric.
