You may know that last semester about fifty percent of the students en- rolled in my course failed it. Let me explain how this came about before you jump to any conclusions. In the first place, since this is a composition class, I expect nay students to follow certain rules of formality. Unfortunately, many students today dislike having to follow rules of any kind, especially those which they may feel to be unnecessary. For example I ask that each of your papers be typed and centered on the paper correctly. I count off points for various kinds of mistakes. A misspelled word will cost you 5 points. You've lost 25 points if you've misspelled five words. If you write an incomplete sentence, you've lost 10 points. If you give me two complete sentences as one with-out adequate punctuation, you've lost 15 points. I do not accept late papers. You will receive a zero for any theme which you fail to submit on time. I expect you to read each assignment. To make certain that you have read the assignment, I will give you a short unannounced quiz from time to time. This class meets on Mondays, Wednesdays, and Fridays. You will have a total of six major tests throughout the semester. Your final grade will be based on an average of these major tests, the pop tests, and eight written themes. If you have ally questions at any time, you can see me on Tuesday. My office is on the second floor of this building. Your assignment for Wednesday is to read Mark Twain's short story on page 75. Friday will be the last class of this week, so you can expect to write a short inclass theme for me then. That's all for today. I'll see you on Wednesday. (27)
