Thank you so much for the advice, everyone. I will definitely update with what happens.
Thinking about it, all my other classmates are probably just as (or even more) anxious than I am. All the tips given do help me feel more confident about speaking. Practicing is a very good idea, I'll try to ask others to be my audience.
Oh, and by the way, the topics aren't related to things that we necessarily studied. Though how I wish that they were.
Thanks again, everyone! I appreciate it very, very much.
