<p>I got my score report today, and I saw that I had a "5" on AP Calculus BC, but only a "4" on the AB subscore? Is this even possible?</p>
<p>Isn't your BC score basically: AB + BC [cal 1 + 2]
and you AB score, just the AB portion? [cal 1]</p>
<p>So how do I get a 4 on AB, and then all of a sudden get bumped up to a 5 on BC...where did the extra percentage or raw points come from to bump me up?</p>
<p>Also isn't BC "harder" than AB, so how do I get a lower score on an "easier" topic?</p>
<p>Do you guys think I'm ready to take cal 3, and linear algebra at college? I don't want to fail or do bad because I got a 5 based on a "glitch" or something</p>
<p>lol...I'm NOT complaining, a 5 is a 5 is a 5, but just curious, that all!</p>
<p>Ok, I actually am not sure AT ALL, but what i do remember from when I took it is that there are certain questions designated as AB or BC questions, and the scores for each are developed from each type of question..</p>
<p>but i culd be compeltely wrong, so this is just a possibility!</p>
<p>Well, it's possible if you did well on all the BC topics (series, etc...) and somehow managed not to do so well on the AB/BC topics together - which is everything else...</p>
<p>It's not impossible. There are 3 scores to consider, 2 of which you see: your exam score, your BC subscore, and your AB subscore.</p>
<p>3 FRQ were shared between BC and AB - thus, 3 FRQ are considered BC and 3 are considered AB. The multiple choice we'll pretend is equally distributed, and that means something like 26 questions count as AB and 26 count as BC (I forget the number offhand, I'm assuming 35 noncalculator and 17 calculator).</p>
<p>Your AB subscore is determined by your raw score on AB questions.
Your BC subscore is determined by your raw score on BC questions.
Your AP Calculus BC exam score is determined by your total raw score.</p>
<p>You did well (enough) on BC topics and did not do as well on AB topics.</p>
<p>I got the same score (BC-5, subscore -4 )! But last year I took Calc AB by itself and made a 5, so i'm hoping it shows that I'm smooth with calc 1.</p>
<p>According to AP Central, 60% of the exam is used for the AB subscore. That would mean that of the 45 multiple choice questions, approximately 27 would have to do with AB topics. (I'm not sure that this is the exact number.)</p>
<p>Also, while the three overlapping questions between the AB and the BC exam count for the AB subscore, if memory serves, parts of one other question count for the AB subscore as well. My guess is that BC5 (a) and (b) served this purpose on the 2008 exam.</p>
