2 more files added to help students review for exam 1a

The following 2 files have been added to Electronic Reserve:

• 07 to read - (from 2/14 class) Delmar Dog Butler video 
• Exam 1a review: 01-07 clicker slides + extras + delmar dog butler video slides

I regret that we did not get through everything I intended today, particularly in the 10:15 class.  Our pace will return to normal next Thursday.

Please be sure to come to Tuesday's exam at your assigned time.
