Even though you say you're not nervous, clearly there's something going on with you once it's Showtime. Give yourself something that will Get your adrenaline up and force you to keep calm. Maybe try doing 34 minute sections for PTs.
@josephellengar: Thank you so much for responding, I feel a lot better about the 4 section tests I have in my schedule. I also really like the advice on meditation, look forward to implementing that.
Biggest takeaways for me was reinforcing the idea of a nice sleep schedule and meditation. Definitely going to be practicing those over the next month going into December.
