I'm starting my master's thesis work with a new professor and had a really bad meeting with them recently. They asked me questions I am supposed to be able to answer, but I was so stressed I couldn't think. I couldn't write stuff on the board. It was just a mess.
He said some things that made me feel pretty bad about myself and I really don't want that to happen again in the next meeting. Could someone please share their ways on how they prepare for research meetings they are nervous for?
