Please feel free to use the sample quizzes and tests below to help you study for this class.  I have arranged the quizzes and tests by subject matter.  These are quizzes and tests that have been given by me in MATH271 at Longwood University.  Note that prior to Spring 2008, MATH 171 was NOT a prerequisite for MATH 271 thus we spent a good amount of time in the class covering some of that material.  This will not be the case for MATH 271 classes taught after Spring 2008.  Thus I have the following disclaimer:  These will not be the same quizzes and tests that you will have in this class and may not cover the same topics  in the same order as your class this semester .
