<p>all d was asking was to confirm it using Lagrange error</p>
<p>Yo does anyone remember what the free response questions themselves in the section A of the BC free response section? Jus gimme one word and ill remember it… i know there was one about snow and one about a zoo… what was the other one???</p>
<p>FRQ 6 took me forever because I kept thinking the -1 was inside the cosx.
Damn misleading questions, I should email CB about this.</p>
<p>^^^ and you didn’t even need to multiply it out. that part was pretty easy</p>
<p>joey - area, rectangle</p>
<p>I took AB and I think we got a harder test than usual as far as the FRQ goes. I had no clue how to do number 6. I think that there will be a pretty decent scale on it. Hopefully I did get a 4. 5 would be awesome, don’t think it happened though.</p>
<p>woah-woah…</p>
<p>after reading joey’s post:
is ab and bc free responses are the same?</p>
<p>Answered all 45 on the MC, prolly got 43 or 44 right.
FRQ was easy, you just needed to time yourself correctly if you didn’t know exactly what you were doing. Probably 52/54’ed that section.</p>
<p>Easy five.</p>
<p>Yea Joey, those were definitely on the AB exam.</p>
<p>AB</p>
<p>Probably got a 38 on MC. Have no idea about the FR…it could be anything. What do you all think will be the lowest score to get a 4?</p>
<p>For the last FRQ, it helped to know what the cosine series was (1 - x^2/2! etc) and then also the last one (d) just use the next term omitted since it’s an alternating series. For part b just take the antiderivative of f (or something like that … don’t remember it now) and then part c was just analyzing g.</p>
<p>I took BC and our proctor called 5 minutes left on Part A of free response when there were really 14 minutes left on my watch (and I was just starting question # 3), so I freaked and made a lot of stupid mistakes, didn’t finish the question, and then when he called 30 seconds I told him that my watch showed we still had 8 ish minutes left and he checked his watch, agreed, but only gave us like an extra three minutes.
So I went back to fix my stupid mistakes on the parts of the question I did get done and even after going back at the end of Part B w/o a calculator, I still didn’t have time to finish the section. I was so mad.
Hopefully though… 22/28 and 15/17 with 38ish/54 on free response will get me a 5. </p>
<p>I thought question 6 on frq was pretty straight forward though. I think a similar question was on a past exam, because certain aspects of it looked very familiar.</p>
<p>I’m not sure how much it will be scaled. I would count on the last FRQ to be scaled quite a bit, some people at my school said they just doodled on the page for that one. I would say probably around 48-50 for a 4, if they are pretty generous.</p>
<p>sounditout, if I were you I may let the integrity committee I think it was called know, because everyone has to have the same time to do each section.</p>
<p>The last FRQ was the same difficulty as other part 6’s I’ve tried in my opinion. Sorry, I don’t think there’s going to be a nice curve. Same curve as usual.</p>
<p>Actually, looking back through my notes, almost the exact same series was used in the 2007 released practice test</p>
<p>My point exactly.</p>
<p>Lol one of the questions in the MC almost got me the An, Bn (5x thingy) one. It looked way too simple, and I was right. Fixed it when I checked though.</p>
<p>BC was not that bad at all. Last one on the FR sorta tripped me up, but I got it. Probably got 2 or 3 wrong on the MC due to stupid mistakes (no surprise there). It was… just like every other practice test. lulz.</p>
<p>The polynomial question wasnt hard. I just ran out of time at the end and I did some integration wrong for part C which in turn affected my part D. Ugh</p>
