Unfair Testing

Government is not my strong suit. In fact, I hate it so much, that I put off taking the course for three semesters. I finally took it this semester, my fourth semester, so I can become a full-admit into my college in the fall. The entire semester was a struggle for me. I hated going to class, I hated taking notes, I could not stand reading the book and studying for it, but I did whatever needed to be done to get it over with.
Despite all of the preparation and all-nighters I pulled before every test, I would do horribly every time, not passing a single exam. The only thing that kept my grade around passing throughout the semester was the paper that we were required to write, which I made an "A" on, and the attendance points I would receive at the end of the semester for not exceeding my alotted absences. With all of my work averaged together, I had to make an 88/135, or a 65% on the final to make a "C" in the class. Considering that this is a higher score than I had received on any of the previous three exams, this would be a task.
I was bound and determined to pass this course, or else I'd be sitting in summer school, when I have way better things to do. I started cracking down and studying hard about a week before my exam. I studied for at least three hours everyday. The weekend before my test, which was at 8 o'clock Monday morning, I studied for 15 hours and pulled an all-nighter the night before. By the time I walked into my test, I was confident that I knew the material like the back of my hand.
I sit down and begin. I flew through the first page and onto the second page and realized that many of these questions weren't worded very fairly. They would ask questions such as "Which of these answers is MOST correct?" There was more than one correct answer on several of the questions. This is not fair. It seems to me that the answer that is "most correct" to one person, may not seem "most correct" to another. The "most correct" answer could almost be considered one's opinion. How am I supposed to know what answer my professor wants? Afterall, more than one of the answer choices is stated in the book.
I have not received my grade for the test yet, but I'm very scared to find out how I did. Why would a pofessor do this to his students? Because of the fact that he expected me to read his mind, I could be sitting in summer school for part of my summer to make a passing grade for this course by August.
