Official AP Physics C Mechanics Discussion

<p>I said almost 100%, but I think you’re fine. As you can see, everyone came back and was screaming how much they have been violated by the exam and how they think they failed. </p>

<p>Where are you going to college if you don’t mind me asking? I need a 5 when I apply to Oxford next year. ><</p>

<p>Imperial College London. I graduated last year, with 16 APs; 8 5s, 7 4s, and a 3 (my final exam, truly did not care about it). I had all 5s in my math and physics, with the exception of mech in which I got a 4 because for the entire 6 months of first semester, I wasn’t in school due to medical reasons. That, combined with a crap teacher, lead to me never even having a reasonable explanation as to what rotational inertia is. I had applied last year to Imperial but given I was in California, I wasn’t able to attend my interview and was turned down. I reapplied this year, sailed through my interview, and was offered a place on the condition that I retake this exam and score a 5.</p>

<p>Oh congrats. Imperial is on my list. I hope you get a 5, because clearly you deserved to get it. I hate conditional offers because it’s so much pressure.</p>

<p>That 2nd question saved me. The third question wrecked me. And did anyone else find the first question OVERLY easy? You know… that feeling where its so easy it cant be right.</p>

<p>thanks for that. I do too. Had I not had my medical issues in the first semester when I applied to oxford (and hence couldn’t study at all for the entrance exam), perhaps I would have gotten a conditional offer there as well. I reapplied this year after having missed the deadline, but I don’t mind in a way. much prefer london, my family is 45 minutes away by car.
as for the question, yeah, i had that same errie feeling. and for i think the third part. i also thought it was two easy, but there were two ways of doing it and both gave me the same answer so i went with it. the last two parts of it though, physically, made no sense to me because of that last sentence. i got some very strange constant for the integral though on q 2.</p>

<p>xAlex I know what you mean!! The first couple parts of number one were soooooooooo simplistic. Hopefully they were worth a bunch of points for the stupid general formulas i included before I started working.</p>

<p>For 1.a) my answer was two lines . . . did I do it wrong?
There seemed to be a lot more space than needed, for me.
Second two parts of 1 were terrible, I didn’t express my answer in the terms they needed because I had no idea how to do it.
The rest was easier than I had expected, but I still didn’t do well.
(I wasn’t prepared and was expecting a much harder one, basically.)</p>

<p>But now that everyone says it was really hard I’m starting to doubt myself.
Can’t wait until we can fully discuss. . .</p>

<hr>

<p>Did anyone get a crapload of Es in the multiple choice?</p>

<p>^exactly 1a and 1b were pretty much just formula plug ins. I was like, hey I’m gonna get a 5, and then I got dominated…Did anyone notice on the mc too, that from #20 onward questions were much harder than #1-19, like so much harder. In total, i probably guessed on 10 mc.</p>

<h1>3 was the worst for me, except for the graph part. I don’t know, i liked #2 because they last part. For #1 i tried to bs the whole right page of that problem, and i think i failed at that too.</h1>

<p>^At 2 points, I got something like EDCB.</p>

<p>in like the first ten mc, i got about half e’s. and i didn’t get that many a’s during the mc</p>

<p>I had hardly any As.
In the end did you guys get ABCD, and then for #35 C? So almost a diagonal?
I also had 3 Es in a row.</p>

<p>(Am I allowed to say this?)</p>

<p>Number 3 was the easiest by far, you just needed to see one thing (the relationship between blank and blank)</p>

<p>

^same here, 3 E’s in a row around the beginning. And yah we can talk about mc patterns. What suprised me from the whole test was the lack of conservation of energy problems. That’s usually on the free response and the mc quite a bit.</p>

<p>@etennis, i thought #3 was the hardest caz i just didn’t understand that one at all, #2 wasn’t that bad, and #1 was hard beside a and b.</p>

<p>^ i kno i love conservation of energy</p>

<p>we can discuss this mad **** tomorrow in detail (all i kno is that this is fckin madness)</p>

<p>You mean Wednesday?</p>

<p>One of my classmates is one of the top 20 physics students in the nation. He had a lot of trouble with FR #1f.</p>

<p>I think that testifies to the difficulty of it…</p>

<p>Hopefully they’ll make the curve ridiculously low after seeing all of our results.</p>

<p>What??? You had to use conservation of energy on quite a few of the FRQ…</p>
