Pleasing the Teacher.

Many times, I've received papers full of the professor's correction. By the time I had in my final draft, the paper looks exactly as if the professor has written in himself. Student's are often in conflict with themselves. Do I write what I really think or do I write what my teacher wants to read? Because my grade depends on it, of course I choose the latter. I mean, who wouldn't? I had one professor who asked her students to critique a book. When my critique questioned the credibility of the author, she returned my paper with soooooooooooo many red marks, I thought the paper had gotten shot! My second draft was much different of course. I wrote it praising book. When your at the mercy of a professor, what else can you do?
