english final

I am so nervous for the english final. I hate giving presentations. I dont know how I am going to do it. The whole 45 minutes is going to be torture for me. When ever I have to talk in front of the class I forget everything I am supposed to say. I have everything all together before I go up and once its my turn, everything falls apart. I feel dumb when I have to talk alot about things I dont know that well or I am not interested in. I always think that everything I say in a presentation is so pointless and meaningless. I would way rather take a written test for the final instead.
