### Exam Problems and Solutions

These exam problems are intended for you to demonstrate your personal mastery of the material, and should be done alone, closed-book, with just a calculator, the two permitted reference tables (periodic table, physical constants), and one 8 1/2" x 11" aid sheet of your own creation.

After you’ve taken the exam, watch the help session videos below for insights into how to approach some of the exam problems.
