# Physics 163 First Semester Review

This web page provides links to online resources which will be useful for preparation for the first semester final exam. Each individual concept is categorized according to subject and linked to relevant pages at the GBS site. The number of questions pertaining to each subject category is listed in parenthesis. To perform well on the first semester exam, you will need to internalize the meaning of the listed concepts. These concepts will have to be utilized, applied and connected. In addition to this review sheet, there is also a series of practice questions with accompanying answers.
