These labs have multiple goals, primary the following:
You should sign up for a lab during the first week of classes. Each student is assigned to a lab section. You are welcome to attend other sections, although people officially in a given section have preference should an instance of that section be overcrowded.
There will be weekly lab web notes, but no graded assignments beyond the homeworks distributed in lecture. You may be held responsible for knowing any information from the labs, except for that which is explicitly indicated as supplemental.
Lab handouts will be posted here as they become ready:
Previous years' labs cover essentially the same material, but with possibly different presentations: S99, F98, S98, F97, S97, F96, S96, F92
