Read the case study below and choose the best possible answer to the following questions.
Christopher asks to talk to his professor about the results of his first exam in his American history class. Christopher is a pre-law major, and his success in this course is very important to him. He tells the professor that he loves history and always earned the highest grades in his history classes in high school. Christopher has always used the reading, note-taking, and test preparation strategies he learned in class, and he thought he was well prepared for the history exam. However, he acknowledges that he guessed at many of the items on the multiple-choice part of the exam. He thought he had done well on the essay, but he scored only 30 out of the 50 possible points. Overall, Christopher received a grade of 63 out of 100 points.
