What do i want from this class?

what do i want from this class? I'm mainly in it because it is required in any course of study. While in it i would like better my self in one of my worst subjects. I want an A but would be happy with a B. I need to do well in this class to show my self that i am able to write a decent essay. It is necessary to know how to write, most classes require some form of an argumentative essay. Doing well in this class would give me the confidence to write about any paper that i will come across in my college career.
