<p>Hard as hell. For the next week, I will punch anyone that says the word "biodiversity." :P Anyone agree/disagree?</p>
<p>tru dat dude</p>
<p>Seriously, that was super f’ing hard.</p>
<p>Really? I didn’t take the exam but I thought APES was just supposed to be a corollary to the Economy section of AP Bio? What made it hard? Wait nvm, answer this in two days, lol.</p>
<p>
</p>
<p>Random questions. Long FR’s. The FR’s were also structured differently from past FR’s, even that from Form HBP 2011, so that really threw me off.</p>
<p>Wow, so they essentially changed the whole test without it being called for? That’s crap, man. I’m sorry that that occurred.</p>
<p>^Yeah, that and there are some strange changes in the administration of late tests that threw me off</p>
<p>Were the changes for just APES or all late testing? What changed?</p>
<p>I read princeton review and probably missed at the most 25 on multiple choice. I knew how to do the last three essays , but the first one i had not idea. i am expecting a four, which is what i need for national ap scholar.</p>
<p>^same. the matching section was pretty hard imo.</p>
<p>Worst case scenario multiple choice score: 64%. I’m sure I got a decent number of guesses / unsure answers right, though. The FRQs really sucked. Did anyone else take the derivative for 4d to justify their answer?</p>
<p>
</p>
<p>Hehe, I love calculus. I even explained what I was doing (taking derivative, setting equal to zero) just to make sure the graders knew what I was doing. No idea how to do that part without calculus (maybe knowledge of logistic growth?).</p>
<p>But I’m glad Keasbey found it difficult; that means that the test wasn’t easy.</p>
<p>I’m a strong AP Chem student and found the some of the matching sections abnormally difficult. Also the first FRQ was really weird- I mean my answers just tried to use common sense and nothing I learned in APES…</p>
<p>However I thought the rest of the exam was pretty fair. Rest of the FRQs seemed pretty broad which made them easy to answer. The growth FRQ was a little strange but I didn’t have a problem with it. MCs seemed pretty standard, for the most part, though maybe a little more difficult than practice exams I had taken.</p>
<p>On 4d, I knew the answer immediately but didn’t know how exactly to explain why it was the answer. I was tempted to take the derivative, but instead I just talked about the shape and slope of the standard logistic growth function. Hopefully an acceptable explanation. Either way, did not seem like an appropriate question for an APES exam… I can imagine some people just randomly plugging in numbers…</p>
<p>it was a quadratic , you just had to find the vertex of the parabola. no need to differentiate it</p>
<p>^^I take it that the POI occurs at half of carrying capacity for logistic growth?</p>
<p>^ that is right.</p>
<p>Yep, steepest slope/maximum of the derivative is always halfway to carrying capacity. Makes sense if you think of the “S” curve of the logistic growth function. Growth starts at zero, increases up to halfwaypoint, then decrases back to zero at carrying capacity.</p>
<p>By the way, in regards to yours/others’ hypothetical posts about the average slope percentage or whatever, I believe it is the basic slope formula converted to a percentage. Thus, change in height divided by change in distance times 100. That’s how I would do it anyway, not that we EVER even briefly mentioned that in APES (review book either). </p>
<p>My math came out evenly on #1 because I used this formula. The math on #2 definitely did not come out evenly though, and I rounded to two decimal places. Stupid long division. Though I’ve seen far more frustrating manual math on practice FRQs so I’m not complaining.</p>
<p>
</p>
<p>Oh, that’s why they gave that scale. **** **** **** **** **** There goes my 5. -____-</p>
<p>That entire question was just outta left field. A contour map? Seriously?</p>
