General Information

 There are several excellent texts available that offer different perspectives.  The books on reserve in the library are listed below.


Extra Practice Problems:
The recommended textbooks have additional practice problems. The book by James Wolff and the book by Reif and others have the solutions in the back or the book. And the text book by Kittel and Kroemer has examples that can serve as practice problems. The recommended textbooks are available in the library if you do not have them, also on the reserve shelf. If you look up the topics covered in class and go through corresponding problems and examples in the text books that will give you additional practice for the materials. Also, it will help to redo some of the homework and discussion problems to get more practice. Hope that helps !
