Me, a TA? That's unpossible!

So I got the call from Dr. Hodson and I'm officially a TA for ENSC 410. Part of me is relieved because I will be making enough to cover most of my expenses now and possibly have some saved over for my potential trip to BC. On the other hand, I've never TAed before so I could be one of the worst TAs EVER! The worry I have is that the TA is expected to ask questions and I'm not known for asking good questions. Silence will not be an asset in this case. Only time will tell how this pans out...or until I hear whispers behind my back from the 4th yrs...
