I have never crossed that bridge, but I think what you can do is not get anxious (at least try not show it in your presentation, mainly when speaking).
There are ways to keep calm, a smile (they say) force the brain to think everything´s okay, and attracts empathy. Medidation can help, and focusing into something else, not that you will avoid eye contact, you can do that and at the same time don´t think the other people is out there to get, relax is the key. And I don´t mean you stare others in a confrontative way.
If you have studied until now, you are ready to that. So, go and get what you worth.
Let others speak, wait your turn, it´s a good thing (so you can let it sink in, and then you answer). And when you are making a presentation, make some pauses (not looong pauses), speak with a steady voice and pace.
Everything will go well.
Now the ball is on the court of the Experts...Let´s wait for further comments.
