Have any of you done something like this before? If so, do you have any suggestions how to alleviate the tension?
I've already practised once before my parents and a friend of the family who helps students with this sort of thing at another department of the same university. This went pretty good. But now I'll have to do it before a much larger audience who, thanks to my avoidance, are mostly complete strangers. Also, I expect that speaking up is going to be a problem.
Any advice and encouragement would be much appreciated.
