AP Calc BC - Difficulty, funny/horror storys etc.

<p>Ill start:</p>

<p>Difficulty: MC without calculator was pretty hard, I was really pressed for time and bearly finished all the questions. MC with calculator was a joke, finished in half the time, spent the other half checking my work and working on that crazy series centered about ten graph. FR with calculator pretty easy except for the polar area part of Q 3. Got the answer after calculators were put away so I couldn't evaluate >.< THe rest was OK, kinda messy arithmetic on the last one though.</p>

<p>Stories:
This first one happened to me lol.
After part one of the MC you can have a calculator for part 2, so you seal off part one with a seal. Me so messed up after the killer part one sealed the entire booklet shut. WITH ALL THE SEALS. Then everyone was getting ready to start, and im like *** how can I start without breaking the seals. I call the proctor over, and EVERYONE has to wait while he breaks the seals. In the end I use an extra seal by tearing it into 4 peices and sealing everything. OMG, I just hope im better at calc than I am at sealing. LOL
Also while we were taking the test, the power went out in the building-luckily there were generators for our rooms so it flicked back on within a couple seconds.
FInally, I heard that someone else had a formula sheet that they made up on their desk! During the test (AB calc). They were caught too, but allowed to finish the test... Pretty sure his score's getting canceled though o.O</p>

<p>Anyone else with comments/stories about the test?</p>

<p>lol, that was funny :-)</p>

<p>Horror story: I found the the area of the wrong section on the free response question. 9 points and my hopes of getting a 5 down the drain. I should have realized it though when I integrated from 3 to infinity.</p>

<p>LOL ^^ DOn't worry, that question probably won't affect your grade that much. Its probably only a couple pts anyway: one pt work one pt answer.</p>

<p>Oh just remembered, I know someone who had their calculator in degree mode. After I heard this I rushed to see if mine was too....PHew it wasn't. Slightly better chances for a five now =)</p>

<p>The guy next to me drew a ladybug in the polor coordiantes function.</p>

<p>I found the wrong area for the polar question and BS'd the other two sections. Definitely a 0 out of 9. So sad, because I made an easy 5 on the practice 2003 exam. Oh well. I only need a 4.</p>

<p>Some kid in my room got a bloody nose and bled all over his test during the MC section. Furthermore, seven kids simultaneously found out that their calculator variables (a,b,c,etc...) were all set to = 0, locked, and archived. I am proud to say I survived through that and thought that the test as a whole was easy.</p>

<p>LOL, thats getting a 5 for sure</p>

<p>^ Hahahaha</p>

<p>During the free response part, I just gave up and began drawing flowers and funky designs all around the border. Then I wrote "I love Calculus" everywhere. My friend fell asleep halfway during the test, woke up, and then wrote a short story for the graders to read in her free response booklet.</p>

<p>haha i did something similar..i was trying to find the area between the curve and the horizontal line, and tried integrating from - to + infinity. (i thought it was one of those indefinite integrals). i ended us getting frustrated with it and skipping it, and then came back to it later. i got it right afterwards though! (i hope..)</p>

<p>^^I did that improper integral thing too. Realized after we had to put our calculators away, and couldn't evaluate for the inverse trig thing.</p>

<p>Ugh found the wrong area for R on FR #1 part A which screwed me for B and C... Think I'll get any partial credit? I had the limits of integration on every single integral wrong because of R. But I had the right formulas for rotation... any guesses on how many points I can salvage from what should've been a surefire 9?</p>

<p>Also, on FR #2, the water problem, I subtracted the water leaving from 0 to 7for part A for some reason... there goes another sure 9.</p>

<p>Screwed up FR #3, polar area pretty badly. Was so confused on the second and third parts. Hoo boy. Expecting a 2, maybe a 4 at best.</p>

<p>Taylor series, FR #6, expecting a zero on that. I wrote for part D, "ALTERNATING SERIES MEANS THAT THE ERROR HAS TO BE LESS THAN 1/200" in all caps. :(</p>

<p>My friend wrote for FR #6 part D, "The Lagrange Error Theorem says so. If I knew more about it, I could actually tell you why."</p>

<p>A friend who was taking AB gave up after the second FR... He went back to the first FR and wrote, "Don't even bother wasting your time with reading my FR's."</p>

<p>Um, the guy who sat in front of me told me he was gonna stab me in the leg if I put my foot on the back of his desk again. Definitely kept my foot off of his desk after that. </p>

<p>All in all, a terribly difficult FR and my hopes of a 5 are gone because I threw away two free 9's.</p>

<p>hey krazyhead00 are u from troy high school?!</p>

<p>during the free response my friend wrote a note to the college board on how he prob failed it like the physics one...and said until next time college board</p>

<p>A friend of mine didn't zoom the window out for #1 far enough, so he thought the function went off into infinity at x=0. Which left some pretty interesting answers for the revolution parts. =P</p>

<p>I just imagined this REALLY BIG DISK with a hole right in the middle... split the universe in half or something.</p>

<p>jumpman5050 and all others that did the same,</p>

<p>Now I don't feel that bad... Well I still do; I should have noticed that they asking us to integrate from -inf to -3 then -3 to 3 and then 3 to inf was fishy... (I do, although, think the problem was poorly worded.)</p>

<p>This may sound a little nit-picky, but I put 10.371 instead of 10.370 for the answer to the polar coordinate problem. College board is real picky in how you round and I was being stupid and rounded 10.37047.. up because my stupid TI-89 shown it as 10.3705...</p>

<p>I also did not justify some problems well enough...</p>

<p>College board does not require one to round, just to truncate. This is why, if you look at FRQ score sheets, they provide something like .370 or .371 if the actual value were .370934.</p>
