In class criticism

I am pretty sure I have a clear understanding of most of the types of criticism. I am more confident in what I know/understand about feminist, historical, reader-response, and marxist criticism than I am the rest; however, that is most likely because I prefer those. Like I said, I am comfortable analyzing text using the criticism's; however, for in class assignments, I am not as comfortable writing. I do better when I can write/read out loud and in my own place. It's something I have to work on, but it still doesn't make things easier. Therefore, although it may not seem like I can write, I promise you I can. Just not in class, apparently! :)
