Complete assigned homework soon after class demonstration. Bring homework assignments to each class meeting. Keep backup copies of all materials created. Keep all items returned to you until after you receive your final grade for the course. Turn in all homework when it is collected even if it isn't complete.
Partial credit is better than no credit.
Actively participate in class by taking notes, following the demonstration, and asking and answering questions. Communicate with your instructor at the first sign of trouble. Waiting until the end of the semester limits the options that are available to you. Be honest with yourself about the amount of time you can or will give to this course. Read and understand the syllabus and clarify any questions you have with your instructor as early in the semester as possible.
