xviiiPREFACE■■Do not kid yourself! Avoid denial. Many students observe their instructor solveproblems in class and think to themselves, “This looks easy, I understand it.” Doyou really understand it? Can you really do the problem on your own without havingto leaf through the pages of a chapter? Although there is nothing wrong with usingexamples in the text as models for solving problems, you should try working a problemwith your book closed to test your level of mastery.We realize that many students are embarrassed to ask for help. It is our biggest challengeas instructors. You must find a way to overcome this aversion. Perhaps contactingthe instructor directly would be a good starting point, if asking questions in classis too anxiety-provoking. You could be pleasantly surprised to find that your instructordoes not yell, scold, or bite! Also, your instructor might know of another studentwho can offer assistance. Peer tutoring can be very helpful.Frederick J GravetterLarry B. Wallnau
