Denied unemployment, how do I appeal?

I got a denial letter last week saying I left my job voluntarily, but I was let go as a teaching assistant. I have been trying to stay organised about it. I have not done a hearing before and I am nervous. Did you bring documents or only talk?

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.
