The lab discussions will begin promptly, so be on time. If you meander in 15 minutes late, the instructor will not oblige you with a personalized individual lecture, and your work group will get pretty tired of having to explain everything to you that was just explained to them. Be considerate of your instructor and classmates and be on time. Work in groups. While rugged individualism may be the American way, it won't get you far in lab.
Most exercises are such that they require a minimum of three hands or six eyes.
You may choose your own lab partners, but you also must assume the responsibility for your selection. If you are having a conflict with a group, either work it out or excuse yourself and join another group. You are not required to work with the same people each week. Occasionally, you will be required to work as a group and prepare a single lab report for submission. Pay attention and no one gets hurt.
