# Midterm Exam

For preparation, I am providing the midterm exam from Fall 2015 and the practice exam that I gave to students. The form of our in-class midterm (on Tuesday, October 4 at 11:00) will be similar.

Now that you have written the midterm, here are links to the test and solutions:

# Final Exam

The final exam is scheduled for Tuesday, December 8 at 12:00. The exam is closed-book. It covers material from the first nine chapters of Kittel. This includes the material tested on the midterm exam (crystal structure, xray diffraction, phonons) as well as the subsequent material on electronic band structure.

Below are two final exams from a course I previously taught. The content is slightly different, but they’re a useful study guide. I’ve also included a link to last year’s Phys 725 final.
