This message is for every new and old student who have been using this web site.  You need to JOIN up and become an official member.  It lets you see the Documents section which has all the tests that I used in my teaching career.  It has scores of lecture exams, quizzes, lab practicals, and learning tips.  All the tests have answers.  But you have to JOIN this site to see the Documents.  There's nothing to joining and it's all free.  So join now so I can really help you pass this course.  Thanx alot.  Mr. Flynn
