A student noticed that there is 140 pages of textbook assigned for the class next week.  This will clarify what is required.  You do not have to read cases in the textbook that have not been assigned.  You should read the comments that follow the cases that have been assigned.  You should also at least look through the rest of the materials.  Some of it is very useful.  But most important is that you read carefully the cases assigned and the comments that follow.
