It's really nice to hear you're stepping out of your comfort zone trying to improve yourself. I'm in the final year of my uni too and so I'll have to give several presentations of my dissertation to a huge audience and it's a really big deal. I've been completely dreading about that but reading all these responses from you guys has helped me a lot. It's really comforting to know that there are others out there having the exam same problems, dealing with similar situations. I wish you the very best in your final exam!
