***Official AP Calculus BC Thread 2014-2015***

@blargenshmargen The table you saw was a grading curve for 2008 with no MC deductions for wrong answers (like how its graded now) So its an estimate, probably four or 5 points off at the most.

yeah i realized that, but i didn’t know how to work past that

I don’t think its a big deal anyway, the most it could be worth is like 3 points.

^I have to admit that I was a bit hesitant with the min/max problem because it seemed TOO easy, but I (luckily) also go t that the slope doesn’t equal zero so its ‘neither’. I tried adding ‘y’ over to the other side but that didn’t do anything…only after my proctor called time did I figure that maybe there was a way to integrate the slope field values into it. It also took me surprisingly long to graph all the points on the slope field because I kept on messing up the subtraction :P.

I thought non calculator mc were decent, calculator mc were challenging, and free responses were fairly easy. Weird because on practice tests i felt the calculator mc were the easiest.

So finally finished this last bit of my highschool schoolwork

I have Form O. The MC part was surprising easy. When I was doing practice exams out of the Princeton Review book, usually I would have like 2-3 left when time’s up. But on the calculator portion today, I have literally 20 minutes left after I answer every single question and I can almost triple check all my answers… The non-calc part is not as straight forward, especially the last few one. I really have to stop and think a little bit before bubbling, but I still get every one of them answered on time (and actually I got it done exactly in the last second).

The FRQ’s were just the usual FRQ’s, nothing’s surprising… every time we got something surprising.

Except for those surprising few, I actually think the FRQ’s were not too bad. And really I spend a large portion of my time doing some extremely tedious fraction arithmetic (which I am extremely bad in) instead of thinking about the calculus. Really wish they put all these ridiculously time-wasting computation under the calculator part. There were only two parts of the problems that I really get stuck in. I got one of them cleared before time’s up. And the other one I just have no idea what to do…I don’t even understand what exactly that question was asking (and I actually believe that question was flawed…)

Anyway, I feel pretty good on this exam overall. I think I have performed a lot better on this one than on the AP Chem and Phy C’s last year. Hopefully I didn’t make too many stupid mistaken.

Do anyone know if they will post both forms of FRQ online or just one after that 48 hours? Really wanted to talk a little bit about the FRQ but have to wait that 48 hours…

just one.

lol…
Then hopefully they choose form O
Really wanted to discuss those with my calc teacher

I feel like I messed up the whole slope field question because the concavity one was weird…

What are you guys talking about? I thought the FRQs were insanely easy. I scored near perfect on the FRQ section. The non calculator MC was alright. But I have to agree with you guys. The Calculator MC was pretty hard.

Like my post if you had O, mark it as helpful if you had G. That way we can see the majority and see which one they’ll probably release. I can’t react to my own post but I had O, so plus 1 to the O total.

I dont know if im allowed to put this up but… I couldn’t integrate cos(t^2)… I plug it into my damn calculator and it spit out the same thing

Was that for an frq or MC question?

Form O… the non-calculator multiple choice was hard. I guessed on a few, mainly because there were concepts on there that I hadn’t reviewed. A lot of people at my school agreed that the non-calculator was hard, but the calculator was doable.

The FRQs were easy…

@BrownieRalph Everyone had that happen to them. What you need to do is set your limits from 0 to t (what you have to plug in) because sin0=0. When solving for the constant, you should get 1.

Suppose for a Radius of Convergence problem I set up ratios and limit right but I forget to account a component when canceling common things on numerator and denominator and I get an incorrect limit and, therefore, radius of convergence. As in, I knew how to do the problem but I missed a part on a step. Out of 3 points for the problem, how many would AP award me?

@Dorfdude8 I’d say 1/3. I’d stop worrying though, what’s done is done.

@Frigidcold: What math are you taking for junior and senior year?

Speaking of 1/3, wasn’t that the radius of convergence?

^Yup, at least that’s what I got :).
