OMG LITERALLY I FEEL EXAXTLY THE SAME. I was so ready and it felt way harder than I was expecting and I think I’m gonna get a four now…also which frq was #4 was that the slope field one???
@Jennacalc I believe so… it was the only one with a differential equation.
@RHSclassof16 lol… I tried doing that but I couldn’t find a way to write the solution in the form y = mx + b… oh well hopefully that part of the question doesn’t have a lot of weight on it… cause I crossed out everything… probably shouldn’t have done that. 
@dogeater OHHHH… i didn’t think of that at all… thank you very much… I probably wouldn’t have noticed that little detail.
Edit: but isn’t y = 2x- 2 just the second derivative rewritten? and to get y you would have to integrate d^2y/dx^2 twice to get back to the original function? Also, differentiating y = 2x-2 doesn’t get you dx/dy that they provided so it’s not a solution? I’m not sure… but I didn’t think of making d^2y/dx^2 = 0 so props on that…
If the test was harder doesn’t that mean a better curve?
@stoopidfoose What we deem as hard and what the CB deems as hard are not always the same thing unfortunately.
@Jennacalc Yeah #4 was the slope field one. The Slope field was the only part of that problem that wasn’t death.
@erc513 I thought the MC was very difficult (The no calculator part especially). I actually though the Free Response was very easy outside of FRQ 4 and FRQ #6 was kind of hard.
Well the curve doesnt really change too much every year but hopefully they lower it to like a 65 or something for a 5… Idk
@erc513 It’s weird. Apparently 2012 had a really low curve (67/108 was a 5) but the FRQ’s in 2012 I thought were the easiest set of FRQ’s of any year. So the CB is weird like that sometimes. But apparently 55/59 people who took it at my school in 2012 got a 5. (Which is way higher than the average, usually it’s like 60% of people get a 5) but the pass national distributions were average. I think a lot of it has to do with certain teaching styles will be better for doing well on a test one year and not doing well on a test another year for the students who have one specific teacher.
@RHSclassof16 yah you’re right they were! I also think 2013 and 2014 were pretty easy too. And last year they had a very high percentage of 5s so im hoping they dont try and higher the curve because of that!
Second part MC was very tedious especially the question where they ask for the acceleration when the position is 50
I think the level of difficulty of the test was dependent on the way the teacher taught you the material.
But the test was full of FTC which was quite “annoying”.
@RHSclassof16 what was FRQ #6?
@erc513 how do you know how easy/hard it was?
@Eggyolk It’s not exactly the second derivative rewritten. It’s the general solution for what values of x and y give you a second derivative of 0. When you take the first derivative of the line, yes you get dy/dx = 2. But, if you take a step back, it’s actually dy/dx = 2x - y, but with “points” substituted in. Since our function is y = 2x - 2, a point with the x-coordinate of x would be (x, 2x - 2). If we substitute that into dy/dx = 2x - y, we get
dy/dx = 2x - (2x - 2) = 2.
@dogeater ahh… I give you props for that answer… well done
How long did it take you to figure the answer out?
@Eggyolk we took 3 mock tests before this they were 2003 2008 and 2014. Also we got tested on the previous years FRQ once a week. I got a 5 on 2008 and 2014 but they were also a lot easier i felt. The first mock test i took i got a 3 but we hadn’t reviewed anything yet. Im surprised at all the people that dont pass the test.
@erc513 oh… how did you get the school get the full tests? because I was looking for MC questions this weekend and couldn’t find anything.
@eggyolk Im not sure. I couldn’t find any online only the answers to them. But my teacher has like every years test. Your teacher probably does to cause they get released every year i just think its a copyright issue putting them online.
@erc513 I didn’t really have an AP teacher because my school only does IB so my teacher just taught me the extra stuff that I needed to know and gave me a binder full of FRQ questions and 2005 AP test. Maybe the school has to be registered with Collegeboard as an AP school to get the tests?
I had to rely on PR and Barrons for MC questions. But some of the Barron’s questions were pretty terrifying.
@eggyolk but also with that f(x) problem with the two open circle and the derivative not existing there. Im pretty sure it was supposed to be the bottom circle colored in. I just think that cause i thought that it meant that thats was f(x) equaled there cause you’re saying that f(x) doesnt exist there when it actuality its f’(x) that doesnt exist there… Idkkkk…
@erc513 was the graph at the top of the page f(x) or f ’ (x) ? Also you had Form O ?
I’m going to assume that the graph they provided at the top of the page is the original function f(x)
I’m going to refer to the derivative of the function as f ’ (x) instead of f’(x) to avoid any misreads.
At that point f(x) exists but f ’ (x) does not exist. I believe they asked for the graph of f ’ (x). At that point, f ’ (x) should not have a value because the derivative does not exist.
If
@Eggyolk uhhh it was f(x) and the bottom one was f’(x). And yah there is only one test form o
@Eggyolk Maybe around 5-7 minutes. Initially I skipped it because I couldn’t think of anything right away, but I came back after doing part a of the next question and I solved it then.
@erc513 yeah, then at that specific point, the derivative does not exist so there shouldn’t be a value for f ’ (x) at that point.
Having one circle filled in and the other not filled in means that THERE IS a value for f ’ (x) at that point when there shouldn’t be a value…
@dogeater I left that question for the end and spent the remainder of the test trying to figure out something… anyway good job on that and hope you do well
