First among these steps should be coming to office hours for assistance as soon as you are having trouble, not the last week of classes. The instructor will meet all scheduled office hours, substitute other hours if office hours must be cancelled on any given day, and make reasonable appointments with students whose schedules prevent them from meeting posted office hours. This time is to be devoted to assisting students. Because of the size of enrollment and my many other responsibilities, I cannot serve as any one student's personal tutor. However, I will assist you in seeking tutorial help from former students who have been successful in this course.
Students are responsible for organizing and studying course material.
This is part of the learning process, and it includes determining for oneself what is key, central material and what is secondary, what is presented as an example of a larger principle, and what is the larger principle, etc. I assume you arrive at the class eager to learn all sorts of new things. The instructor is responsible for providing reasonable assistance to the student's learning process. The goal of providing assistance is to help you understand the material, it is not to help you guess what might or might not be on a test. Students are expected to come to class prepared and on time, ready to discuss and ask questions, and interested in learning the material.
