Exam 1 will focus on:
   -  the material covered in lecture through 9/16 
      plus file 'temperature.py' on 9/21.  

   -  labs 1-3

   -  assignment 1


But go through the code for all lectures, to get more practice with
problem solving.

A sample exam and solution will be given to you on the course
schedule.

**Be sure to take the sample exam first, before looking at the
  solution.  It will be much better practice that way.

Since the sample exam only has 4 questions, this is only a sampling of
the material we covered.  Don't just study the material on the sample
exam - be sure to study everything.

Actively study - read and understand code we went through.  Trace the
code on paper, then check yourself in Wing.

Descriptions of some functions and methods will be given to you.
So, be sure you can understand such descriptions well enough that you
can use the functions and methods.
