Practice Exam 3
Below are sample questions from your book (of which all of the answers are in the back). These
are not necessarily indicative of the specific material or types of questions that Drs. Hofmockel
& Serb will ask on the exam. Remember, they want you to be able to apply your knowledge of
the material learned in class and from the book and part of that comes from understanding the
significance, application, and importance of that information. The majority of questions will
come from the learning objectives so focus on those more than anything else! Good luck!
