AP Calc AB Exam – Last Minute Tips Study the “Stuff You Must Know Cold” Sheet – and know it… Cold! Multiple Choice Answer all questions! – you do not lose points for guessing. Look at the answers before you start solving; they can guide you or give you hints. Skip hard problems and come back to them (choose an answer, but mark that it was a guess). Be careful with details – your wrong answer will most likely be one of the choices. Free Response If you use your calculator to solve something, WRITE THE SETUP. Use the graphing calculator to only do the following four functions (otherwise, show your work): o Graph functions in an arbitrary window, o Calculate zeros of a function (either by graphing or algebra), o Calculate the derivative of a function (write the derivate), o Calculate the integral of a function (write the integral). Answers must be correct to 3 decimal places (rounded or truncated – you may give more). Sign charts are not sufficient for justifying extrema with 1st Derivate Test. In order to best fit your graphs on the calculator, first adjust the domain (x-values), then Zoom-Fit. You do not need to show intermediate steps – if you do show them and make a mistake, but get the right answer, you can lose points. You do not need to simplify expressions. Make sure you are answering what they are looking for – e.g. max value is the y-value (or f x ), value where max occurs is x-value, you need x, y if asked for coordinates. NEVER USE PRONOUNS (“IT”) – be specific; state which function (e.g. f , g , f x , f x ) or the exact interval. Don’t forget C on indefinite integrals. Show all work – the grader is not interested in finding the answer, he is interested in seeing if you know how to solve the problem. Do not round partial answers too soon – store them in your calculator or go at least 6 decimal places. Do not let points at the beginning keep you from getting points at the end: o If you can do part (c) without doing (a) and (b), do it, o If you need to import an answer from part (a), make a credible attempt at part (a) so that you can import the (possibly wrong) answer and get your part (c) points. Do not waste time erasing bad solutions – if you change your mind, simply cross out the bad solution after you have written the good one (crossed-out work will not be graded – if you have no better solution, leave the old one there; it might be worth a point or two).
