```Below is a list of topics that you should know to do well on the first test. While I don’t
know what will be on the test, these topics are at least what you should know as a base. I
have also listed a few problems out of the book that help illustrate these points. Make
sure you understand how all of the group/individual problems/quizzes are done. I also
recommend buying the sample exams and solutions packet prepared by the Society of
Physics Students available at the Target Copy Center
