The labs are self-contained. You must read the lab before coming to lab class. Some labs will not be 'in sequence' with the lecture. There will also be a short quiz before each lab to insure the student is properly prepared for the lab. You will be expected to have a pre-lab at the first lab.
More detail is given in the lab manual about lab lab grading.
Make up labs are only given for officially excused absences. If circumstances permit, you may be able to do the lab in another section. This must occur during the same week as your normal section and only with approval of the lab supervisor. Problems at the end of each chapter plus handouts are assigned weekly. These problems are due at the beginning of class on Friday morning.
