The Class Lecture Notes are designed so that you can easily edit the notes by filling in the "holes" with the material presented in class. They are not provided to encourage you to skip class, but to make sure you get the most out of your lectures and can listen to more of the material presented. You need Acrobat Reader to view and print the lessons. If you do not have Acrobat Reader on your computer, simply visit the Acrobat Reader Home Page where a free download is available.
