Yup, I had an experience in extemporaneous speech. At first it will really make you nervous especially if you don't have any idea with your topic but it's fun. Ours is you're going to pick a random paper put in a box and then you will be given for about 1 minute to think and to prepare for your speech about that certain topic. The speech is about 1 to 2 minutes. You're just going to share your opinions, your ideas, and if you're going to agree on that topic or not. I tell you, just don't be very very nervous, just be confident and trust yourself no matter what so that you can make it.
