I hadn't thought of this. I had to do 3 presentations in school. The first was whatever we wanted, the second had to be a technical aspect of the class studies, and the third was about our final project. The first one wss tough, I thought i might pass out. But it was nice to talk about something I loved...bikes. The second one wss am absolute nightmare. I was forgetting things I wss so nervous and getting so stuck on things. By the third, I was still very much nervous but overall in a better place because I knew the people more. I say embrace it. It'll probably be tough but it may help you deal with the stress and general concern. Know your subject matter, stand up there confidently and slay it!
