During each lab session throughout the course, your demonstrator will be observing you and making notes on how you perform in the lab. At the end of the course, your demonstrator will base the In-Lab Mark on these observations.

Criteria for In-Lab Mark. While the criteria for arriving at the In-Lab Mark will overlap to a great extent with those for the Experiment Mark, the In-Lab Mark is meant to provide a more general overview of your work, with particular focus on your experimental ability. It will allow your demonstrator to reward those students whose notebook skills may be poorer than their experimental ability and creativity. In arriving at this mark, your demonstrator will take into account: the way you approach and organise your experimentation, your efficiency in planning and setting up the experiment, your ease of learning to use the equipment, evidence of graceful handling of instruments and equipment, and your care in taking data. Also considered will be: your ability to estimate errors (rather than calculating each one exactly), your ability to distinguish the essential from the inessential, the way you work with your partner (if you have one!), your willingness to try something, to make a mistake, and to learn from it, how often you seek advice and ask questions. Vital in good experimenters is the ability to squeeze the maximum information from their data, the curiosity to ask the difficult questions and to follow and try to explain unexpected results; your demonstrator will be on the lookout for such qualities in his or her determination of the In-Lab mark.
