Instructions:  This page includes a sample of questions relating to material convered during the first two weeks of class.   You may answer as many or as few questions as you wish, in any order.   When you are ready to check your performance, scroll to the bottom and click the 'Submit' button.   All questions you answered will be graded, and your score will be shown at the bottom of the exam.   You can also retry questions that you missed by using the link at the bottom of the page that shows your results and this process can be repeated.   This 'drill' system is under development. Please contact Dr. Wilson (h-wilson@tamu.edu) with problems or comments.
