<p>Same here !!! Talk!</p>
<p>I had form O as well. The multiple choice for the no calculator part was harder than usual. I thought the calculator part was extremely easy. I bombed one of the free response questions but according to ap pass, I can still easily get a 5. </p>
<p>When can we discuss specific questions (or are we allowed to?).</p>
<p>i thought the test wasnt too bad, besides one question i totally screwed up. i definitely liked the new format too</p>
<p>I’m pretty sure we can discuss question specifics, as there are tens of thousands of views and hundreds of comments regarding the questions of the May 5th SAT in the other forum so It should be alright.</p>
<p>What did you guys get for the related rates problem in the calculator section? it was about some guy walking away from a telephone pole at a rate of 4 ft/sec or something like that and it asked for the rate of change of his shadow? I guessed A, which was like 1.5 ft/sec</p>
<p>I thought it was all relatively easy. Everyone in my class had finished the calculator mc and gone to sleep within 20-25 minutes. 50-55minutes for what like 17 questions was insane especially since many of them you could graph on your calc and find the answer within a matter of 10 seconds. The FR really wasn’t too bad for me either I can’t remember the specific question and idk what is safe to say but part C of the one about the bird I know I missed.</p>
<p>were not supposed to discuss free response until questions are released 48 hours after the test…and since i think i got a 5 i’d rather not take my chances</p>
<p>I had no idea about that question. I just put 2.666, lol</p>
<p>Ok can someone verify this for me? Apparently AP uses the same exam writer for 3 years…which is why 2012’s questions were similar to last years.</p>
<p>Seriously, that egg question(#5) was pretty much the same thing from last year’s landfill problem.</p>
<p>For the last part of #5, did you guys get the constant to be -ln(81)?</p>
<p>I thought the test was super easy. There was only one question that I didn’t get, which was the one usnfilms just asked about. And, I also guessed A.</p>
<p>@SDFGXH
I do remember getting -ln(81) for the constant in last part of #5.</p>
<p>@johnhughzy
are you confident that B. 2.666 is the right answer? only reason I ask is that I guessed and I’m trying to keep track of all the ones I got wrong so I can get a sense of how I did.</p>
<p>Also, (at everyone), there was a problem near the end of the calculator section where it gave you the velocity function and it asked at what time would the particle would return to position 0. I was between D.) X = 1.976 (or something like that) and E.) 2.876 (or something like that), and I ended up saying E. What did you guys get?</p>
<p>It was D, because all you had to do was plug the values into the integral to see which one gave you a displacement of 0.</p>
<p>Wow, I just looked at the landfill problem from last year and I can’t believe I screwed up that one today so badly. I got 2 points prolly, since I only got part a right -_-</p>
<p>well that makes two wrong so far, but they were guesses so whatever. I felt pretty confident on the other parts of the test.</p>
<p>There was one difficult problem on the non-calculator section where you had to get the derivative of like xsin(3x)… or something and I remember saying C. or D. but that was a guess. what’d you guys say?</p>
<p>anyone remember what they put for the one where it was like g is the inverse of f, and f(c)=d f '(d)=a, what does that tell us about g? (wording/notation may not be correct). I remember putting B. but that was another I guessed on. I guessed on a total of 5 problems I believe.</p>
<p>Edit: wasn’t really a guess, but I wasn’t confident I solved it right</p>
<p>Guys, I’m freaking out. I think I got roughly 8 wrong on the multiple choice, and maybe only 88% correct on the free response (this is worst-case scenario.) Would I still get a 5?</p>
<p>Would do you think the curve will be?</p>
<p>^You would get a 5 easily. </p>
<p>xsin(3x) is just product rule and chain rule</p>
<p>I think I got g’(d)= 1/a</p>
<p>I got that too @NeedsHelp ~ educated guess. Thanks for the confidence, btw.</p>
<p>Curve predictions anyone?</p>
<p>i felt like the free response was easier than usual. anyone else think that?</p>
<p>@needshelp1212
Yeah i know xsin(3x) is a product and chain rule but there was more to the problem than that, I just said xsin(3x) because that’s one part that I remembered. some of the answer choices were rational numbers with sqrt cos(something) on the bottom</p>
<p>I also got g’(d) = 1/a.</p>
<p>And I agree that, for the most part, FR was pretty easy.</p>
