Let me know if you find any that are particularly helpful. You will be surprised how much working together on problems and summaries can help. Be careful not to sit next to your study partners on exams in case you have suspiciously similar answers. Please note that the content of exams varies somewhat from year to year with textbook and course pacing. Look at the content to determine the extent of relevance.
Most students are never too sick to take an exam and never consider copying anyone else's work.
I assume that students are honest and responsible in their work and will assume innocence until my suspicions are aroused. So that you will know what your rights and responsibilities are, I have explained below my policies on attendance and cheating. Any student arriving late for laboratory lecture may be denied permission to work in the lab for safety reasons. Forgery of such documentation is equivalent to cheating on the exam or lab. Anyone failing to appear for a makeup will never be allowed the opportunity again in this course.
