Being able to write essays is something you must learn how to do. Although you don't write essays a lot, expect at least two. The two are midterm essays. These are really important to do good on because they count for twenty percent of your grade. Make sure you understand MLA formatting because this is how all your essays are written. Mr. Brock is very picky about your writing because he wants it to be the best it can be. You also always have a chance to re-write any essay so you can get a better grade, but I advise doing well on it the first time so you don't have to worry about re-writing it.
