Yes, the more you do it the easier it gets. I am finishing a class such as this, and it has been an interesting experience. The good part though, is that everyone in the class is nervous too, so you're in good company. One of my fellow classmates had to sit down in the middle of their speech, but they finished it, and I'm proud of them. Frankly I can't believe words came out of my mouth when it was my turn, but it happened and it turned out ok.
