FALL CHE 123 2008 CLASS SCHEDULE

To do well in chemistry and get the most out of classroom experiences,, you should be prepared for each class. I will post reading and other assignments for the next class by 5PM of the class day we just completed. For example, after Class 1 ( 8/31 W), you should prepare for class 2 (9/2) by reading the assigned text and doing the JIT assignment BEFORE YOU COME TO CLASS 2.
