Nervous about Public Speaking class

Hello. So next week I start my last semester and one of the classes I'm not looking forward to is public speaking. Since it's part of my general education requirement, does anyone have any advice, tips or suggestions that they want to share? I'm always nervous whenever it comes to conversation or having to present a presentation or project and my nerves get the better of me all the time. Only times when I'm not as nervous is when I'm around some of my family members or a couple of close friends.
