The Calculus AB Exam CAICULUS AB { CALCULATOR CANNOT BE USED ON PART A OF SECTION I. A GRMHING CALCIILATOR FROM THE .{PPROVED LIST IS REQUIRED FOR PART B OF SECTION I AND FOR PART A OF SECTION II OF THE EXAMINATION. CALCULATOR MEMORIES NEED NOT BE CLEARED. COMPUTERS, NONGRAPHING SCIENTIFIC CALCI.JLATORS, CALCTJLATORS WITH QWERTY KEYBOARDS, AND ET,ECTRONIC WRITING PADS ARE NOT ALLOWED. CALCULATORS MAY NOT BE SHARTD AND COMMUNICATION BETWEEN CALCULATORS IS PROHIBITED DI.]RING THE EXnMINATION. ATTEMPTS TO REMOVE TEST MATERIALS FROM TIM ROOM BY AI{Y METHOD WILL RESULT IN THE INVALIDATION Otj'TEST SCORES. SECTION I Time- I bour and 45 minutes All questionsare given equal weight. Percentof total grade-50 Part A: 55 minutes,28 multiple-choicequestions A calculatoris NOT allowed. Part B: 50 minutes,17 multiple-choicequestions A graphingcalculatoris required. PartsA and B of SectionI are in this examinationbooklet;PartsA and B of SectionII, which consistof longerproblems, are in a separate,sealedpackage. GeneralInstructions DO NOT OPEN THIS BOOKLET UNTIL YOU ARE INSTRUCTED TO DO SO. INDICATE YOUR ANSWERS TO QUESTIONS IN PART A ON PAGE 2 OF THE SEPARATE ANSWER SFMET. TTM ANSWERS TO QUESTIONS IN PART B SHOULD BE INDICATED ON PAGE 3 OF Tfm ANSWER SffiET. No credit will be given for anything written in this examinationbooklet, but you may use the booklet for notesor scratchwork.After you have decidedwhich of the suggestedanswersis best,COMPLETELY fill in the correspondingoval on the answer sheet.Give only one answerto eachquestion.If you changean answer,be surethat the previousmark is erasedcompletely. Examole: What is the arithmeticmean of the numbersl, 3, and 6 ? (A) SampleAnswer @@@(D@ I '7 (B) * J (c) 3 (o)+ (E)I wonderwhetheror not to guessthe answersto questionsabout which they arenot certain.In this section Many candidates of the examination,as a correctionfor haphazardguessing,one-fourthof the numberof questionsyou answerincorrectly will be subtractedfrom the numberof questionsyou answercorrectly.It is improbable,therefore,that mereguessingwill improve your scoresignificantly;it may even lower your score,and it does take time. If, however,you are not sure of the best answerbut have some knowledgeof the questionand are able to eliminateone or more of the answerchoices as wrong, your chanceof answeringcorrectlyis improved,and it may be to your advantageto answersuch a question. Use your time effectively,working as rapidly as you can without losing accuracy.Do not spend too much time on questionsthat are too difficult. Go on to other questionsand come back to the difficult ones later if you have time. It is not expectedthat everyonewill be able to answerall the multiple-choicequestions.
