panic

Ok so I am halfway through the podcast tutorial and am freaking out. It is very informative, but I do not feel confident at all that I can actually do this. Will I do it at the center, what on earth do I have to give of any interest to anyone? Does my windows vista work with the equipment? and will I be borrowing it from school.? I don't have a mac so the music will become an issue. I feel as if I should not be in this class. I have no background on any of this stuff and feel like I am on a sinking ship. I am not confident at all about what I will be doing and am afraid to watch the rest of this tutorial. I am only halfway through and not sure I can do this. I have not even been able to get the video cam to work on my computer, how will I do a whole project. I think that there should be something in the course description before someone signs up for the class. I am not going to be able to learn all of this in this short amount of time in order to finish the clas.
