If you are having difficulty in a course, your first move should be to schedule an appointment with your professor. Although this might seem intimidating at first, it is important to discuss your difficulties with the person who is an expert in this field and will be assigning your grades. Faculty want to help students who are interested in working hard and are academically motivated. Prepare for your meeting by writing down your questions or concerns and bringing along any related materials (text books, exams). Ask your professor for suggestions on how you can improve. Then follow through with these ideas.
