AP Calculus AB Test Discussion

<p>nope. it asked who lives closer to school and that would be caren! poor forgetful caren!</p>

<p>whheex: either way, you don’t account for her going back home after integrating</p>

<p>Nooooooooooooooooooooooo! Well, that’s probably one point off. Oh, wait. What if i am one point away from a five? Oh, man. I probably need that point.</p>

<p>Seriously guys… be more careful about discussing questions. =(
You never know what might happen.</p>

<p>But yeah, number 1 was easy. <em>coughcarenlivescoughclosercough</em> Agreeing with the majority of the posts here.</p>

<p>“is there still an inflection point if f’(x) has a sharp corner(cusp)?” - pg. 5</p>

<p>Yeah, f’'(x) still changes sign over that point</p>

<p>again, lol what did you guys get for the total avg. wait/individual wait time for the concert problem?</p>

<p>Caren definitely lives closer lol. </p>

<p>It asked who lives CLOSER, not who travels the farthest distance to get to school. I love simple questions like that. :)</p>

<p>Edit: Sorry, alicimoo. Uhhhh don’t wanna get ninja’d by the AP Police, so sorry guys, can’t help.</p>

<p>

if you don’t take the absolute value of the integration, the part where she goes home cancels out.</p>

<p>okay, so i have to ask this question for someone. if a person took the AB exam and:

  • answered 18 on MC part 1 (likely all right; no guesses; the rest were skips)
  • answered 12 on MC part 2 (likely all right; no guesses; the rest were skips)
  • got < half credit on FRQs 1-3 and 6, > half credit on 4, and around half credit on 6
    what would be this person’s score approximately? this person is hoping for a 3.
    i feel bad for her, she works so hard atimes and had really hoped for a 5…
    but things just didn’t work out for her this time around, and now she just really wants to pass…</p>

<p>@squadus - I got 300 something and I got 0.3ish for individual.</p>

<p>

MC = (18+12) = 30 x 1.2 = 36
FR = assuming got 5s on all = 5x6 = 30
30 + 36 = 66
Approximately a high 4.
(I believe that’s how you calculate it, I forget if you multiply the FR by a number or not).</p>

<p>i got like 183 or something for the concert. bah.</p>

<p>@alicimoo</p>

<p>Don’t take my word for it haha. The proctor called 10 minutes left and I was still on #2, so I basically rushed #3.</p>

<p>I’m referring to when she went back home to get her calculator/calculus homework, not when she comes home from school everyday.</p>

<p>I like .5 for the individual. haha great we all have different answers. lol</p>

<p>Lol, watch the right answer be like .9 or something.</p>

<p>@alicimoo: okay, thanks!</p>

<p>and this question is for myself and my friend - how generous are the ap graders for those who didn’t quite get the answer right? (for example - messed up on the integral but then solved the integral correctly)</p>

<p>They base their grading on a rubric they have. For example, if one of the parts of a problem required you to find an area of region R or whatever, they would look for the correct integral format, which would be worth like 1 point. And then if the integral is solved correctly, they’ll give you another point and such.</p>

<p>So if your answers are not matched well with the rubric at all, then… ehhh. I don’t think there’s even partial credit.</p>

<p>I got the same answer as alicimoo for those spartans. xD</p>

<p>for the average wait time one…</p>

<p>they gave you w’ and you had to find w, so obviously that was the integral of w’
then, to find the amount of time all theater goers waited it would be w(2)-w(0)
w(2) was 760, w(0) was 0.</p>

<p>the answer ended up being like 0.77 something…</p>
