Practical #1 Questions and Answers

The average score for the lab section #1 (8 A.M.) was only 54%, and for the section #2 (10 A.M.) 63%. These are the lowest scores we've ever seen on any practical . . . You should get your individual scores by the end of the week, after all lab instructors grade their groups, and we adjust the scores.

In meantime, I would like to encourage you to start studying for the next lab. (We'll start working on the brain! We might even get some real human brains for you.) There won't be an entrance quiz at the beginning of the lab, but it's always a good idea to come prepared for the class. That way you'll use your time in the lab more efficiently. At the very minimum familiarize yourself with the following figures from the Chapter 12 in your text: 12.6; 12.12; 12.15; and 12.31.
