Because students often work in groups in lab, absences hurt everyone and should be avoided. In addition, most days there will be graded homework problems assigned. Many students find it useful to keep a copy of the problem to review. No late homework will be accepted and the lowest homework grade will be dropped. If you must be absent, have someone else take notes and hand in any assignments for you.
Students are responsible for knowing material in the assigned reading, problems, labs, and lectures.
Working problems, studying and understanding the material are keys to doing well. It is assumed that the students are familiar with the background material in Chemistry, Physics and Mathematics. While I am glad to help you in reviewing these topics, it is your responsibility to make up any weaknesses or deficiencies you might have. It is not sufficient to learn the material from the lecture alone - you should read and think about the topics covered before attending lecture. If you have tried and still can't get a problem or concept, please see me for help.
