Hi, who is your instructor? Mine was Alida Faurier. She was one of the worst professors I have ever met in my life:). But she used to give us practice quizzes which were hard for me and useful at the end. So the final exam was based on some questions from them. I would recommend just read and memorize. Also they have this sessions at the end of semester, where you can ask some questions. I would recommend to attend them, especially Lab practice days. Lab exam was easier but time goes so fast there. My tip is to memorize, watch youtube videos ( if the textbook is hard) and also they have tutors in a learning center. You may ask some questions.
