"Due to my poor English and lack of prior knowledge, I failed his midterm exam. Ken called me to his office and told me that he understood my situation and would not count the midterm grade if I got a better grade on the final. He then spent a half-hour tutoring me on the concept of power and the idea of "system structure." Among other things, he told me that he disliked the label "neorealism" because he felt that the term told you nothing about the theory itself. Instead, he preferred "structural realism" because it described the substance of his theory."
