Am I in Way Over My Head?

The film "Underground Zero" was great... it was a compilation of 13 films, and they were hard-hitting in varying degrees; many of them stuck indelibly in my brain.

I had to escape out of class in a very inopportune moment to see "Underground Zero" -- we were discussing life and death. I don't know how well I'm going to do in this class, I feel like I'm in way over my head. It's very different from the first Philosophy class I took a year ago, partly by demographic and also the impression that many of the people in that class have taken a number of other PHIL courses. It delves into metaphysics, epistemology, dialectic reasoning, and this is where my head starts to swim... I know this course is good for me, and I'm going to learn a great deal, but realistically, I'm going to have to work very, very hard to get a good mark.
