Fear? Me? HA!

Honestly, since I've been tutoring for a few years now, this semester didn't seem new. However, I am nervous that because I'm a TA/Masters student now, I will be held to a higher standard... or that I'll be expected to just know all of the answers. I am human, and I am still learning. There are things that I am not perfect at, and there are things I do not know. I guess that is my biggest concern/the thing that makes me most nervous.
