I been in the same situation last semester. We need to present every week and it was a nightmare in the first couple of presentations because I was pressuring myself. It is all about your mindset. You need to accept that you need to present this. The fear and pressure just makes it worse. You will stutter or stammer a lot and it is not a problem. For example I was spending nearly 1 minutes to say a sentence. But it is not a problem, i realised that way later. If you can accept in your brain that you can present this you will be alright. After first couple of sentences I am starting doing okay. I am trying to focus on my breath and being calm because i know that i can do this. Just believe in yourself and there is no escape from this presentation. You will do it and it will be alright.
