Presenting in front of others can be very scary, but there are ways that you can take away some stress. Knowing your topic and practicing your speeches before presenting helps. Focusing on the material instead of the audience is a great way to get your mind off of actually presenting. Personally I like to take a couple of deep breaths before presenting. Breathing exercises help a lot of people.
