AP Calculus BC 2011 Thread

<p>o actually i ntered my mult choice worng anyways lol that was just from discussing with friends
hahaha
and 1/3 is fine with me…</p>

<p>What are you guys predicting the curve for a 5 will be?</p>

<p>i think 74/108 is a 5… relatively easy test plus no scoring penalty should make it a rather harder curve</p>

<p>^ that is WAY to harsh. 70/108. i heard the 2010 was really really easy too and the open ended were of comparable difficulty. The removal of the penalty will only make the curve slightly harsher.</p>

<p>how many people took a year of AB before taking the BC class?</p>

<p>Think I did okay, skipped 2 on MC, and went dumb on 2 parts on Free Response. Just hope I dont get a 4, or my teacher is gonna shoot me for ruining the class average lol.</p>

<p>The first non-calculator part of the MC section was definitely tough. I memorized some things to look out for regarding convergence tests, but many of the problems still looked totally alien! I ended up putting “B” as an answer for all the ones I skipped due to the new multiple-choice scoring policy, so hopefully I also got a couple of points there :wink: </p>

<p>For the most part, everything was fairly straightforward except for the question that dealt with the landfill. For some reason I had a major brain fart there - I wrote down some completely stupid explanation that since the second derivative was positive, the rate was accelerating… or something along those lines :stuck_out_tongue: I’m wondering what the curve will be like. At this point I don’t care too much because UC Berkeley even accepts 3’s for credit, but of course a 5 would be nice (though I don’t want to keep my hopes up).</p>

<p>i didnt think it was that bad… lol i swear it took me like 5 mins to figure out the very first problem but then i calmed down :)</p>

<p>and number 6 was probably the easiest FRQ</p>

<p>WOW! Super bi-polar test. Some felt ridiculously easy, and others…. yeah.</p>

<p>Hey, remember not to talk about anything specific! :)</p>

<p>Also, I don’t expect the curve to go up much at all.

  1. Difficulty feels increased.
  2. CB has made some statements about not increasing curves.
  3. IF it goes up, the curve will become more compacted.
    The score increase for a 5 would be a lot lot less than the score increase for a 3. This is because the reduction multiplier doesn’t hurt a 5-score as much because a person with a 5 would miss a lot less questions. Also, the ¼ point on affected ½ the entire test.</p>

<p>So, with the scoring, I think it won’t be too different.</p>

<p>The test was relatively easy. A couple of the mc’s of part a were a bit difficult I thought (e.g the one about the slope of the inverse of g), given the time we had. The first free response I didn’t answer most of, but I did the rest. One thing I couldn’t get was the perimeter of that figure in terms of k only. I didn’t know how to evaluate the integral representing the arc length of the function from 0-k).</p>

<p>Self studied and the test was fairly easy. Pretty sure I got a 5 but I’m never sure until I see the results. Know I got at least 3 9’s on the FR. I’ve just been doing a lot of old released free response questions from previous years, that really helped. Questions 1 and 2 were the exact same from 2005, which is one I worked on two days ago. That was super lucky. Did the first two, and I’m positive they are 9’s, in 12 minutes.</p>

<p>i don’t think you had to evaluate that integral,they just asked to write it down…I also thought that this test was easy,except some MC questions and part d in FR #6…I wish AP Chem exam on monday was this easy…that was ridiculuos:(</p>

<p>Yeah!! haha that’s exactly the same with me. 6)d. I remember learning about the error bound but i didn’t answer it right and i didn’t know how to apply it to a graph. But yeah I wish chem had been this good for me. I mean I know I did well but I made a few stupid mistakes that could cost me the 5.</p>

<p>Honestly I thought the MC was a joke… the questions were so much more straightforward than any of the practice/old AP’s I’ve done. The FR wasn’t bad either except maybe the end of #6… I think I was pretty much brain-dead by that point. I know I made some careless mistakes on the FR part but meh. As long as you were familiar with the types of questions it was a pretty easy test.</p>

<p>The MC section seemed pretty easy- I think the majority, or at least a good percentage, of the questions have shown up on the (released) MC exams before and there weren’t really any tricky ones.</p>

<p>Questions 1, 2, 3, and 5 were all moderately easy. I feel like it was very possible that I could have gotten 9’s on any of them, though right now I’m going to assume I made one or two errors simply because I want to aim for a low estimate.</p>

<p>Questions 4 and 6 were a little bad… I understood most of 6 but I think I made a really bad, minor arithmetic error that could have lost me up to 2 or 3 points, and then there was another part where I had never seen anything like that before, and so I know I lost a few points there. Question 4 threw me off a little because there was a certain aspect of the problem that I never came to a conclusion on, and so I didn’t finish one part and there was another part where I’m pretty sure I did an inadequate job on.</p>

<p>I am still sort of expecting a 5 since, if I got less than 9 wrong on the MC (which, I am expecting much less than that), I could get less than 5 on each of the FRQs and still have a composite score of over 70.</p>

<p>That made me feel alot better about my score…I know I didn’t get too many MC wrong (well, hopefully.) and I normally score well on the FR… so thanks for doing that math.</p>

<p>Felt pretty good about it except for several MC questions and #5 on the FRQ… I don’t think i ever did a problem like parts a and b so yeah left those blank. Other than that it was good. expecting a 4/5… Best out of all my AP’s lol</p>

<p>@ NYJ3TSFAN: That’s more or less my own stance on the test. I’m glad to hear I’m not the only one who thinks that way!</p>

<p>Does anyone know exactly how the score on the MC is calculated? For example, do they deduct 1/4 point for each incorrect answer? Because the instructions on the booklet said that points will be given for correct answers only and no points will be deducted from wrong or blank answers. However, I read from another source before the exam that said 1/4 points will be deducted from each incorrect answer. so now I’m very confused…</p>
