<p>What?!? That test was easier than the tests I've been taking all year. The polar question was very easy if you memorized the area equation for polars( A = .5r^2) and all you had to know for the rest of them were trig stuff like x = rcos(theta). The series question was a little tougher, but it definitely didn't kill me.</p>
<p>heyyy, careful. The last question for the polar was difficult. I couldn't get it. I'm still ****ed off that I forgot the square the radius in the last problem on the first question.</p>
<p>last year's second section free response was generally accepted as as tough as it gets. i remember a similar reaction last year, but don't worry! even if you think you did poorly it's still possible you did well*</p>
<p>*but not as well as last year's BC class at my school! every single student in the class (all 9 of us) got a 5. we're legends! =p</p>
<p>OK I have a question.
Lets say on a hypothetical AP exam, a chart was given and you had to estimate the derivative at a point (use fund. theorem) but instead used a regression line and worked from there. Since the rest of the answers were based off of the regression line, would the whole problem be marked wrong?? Hypothetically, I'm in Statistics and I get some stuff intermixed so regression was hypothetically the first thing that came to mind.</p>
<p>no u would still get credit, but not full</p>
<p>Hmm...how do you use the fundamental theorem of calc to estimate the derivative? It's after the AP so my calculus mind is blank right now.</p>
<p>if they gave you a chart the best estimate would be to use the point before and after and get a slope...i have no clue what a regression line is but it sounds the same?</p>
<p>Take the slope between the point you want and the one before it and the one you want and the one after it and average them. Maybe not fund. theorem, but...</p>
<p>So hypothetically you would still get some credit???</p>
<p>if you do the correct steps in the later parts, but just plug in the wrong info, yes you get partial credit</p>
<p>and for that lin regression thing there might be a chance you get some points for recognizing you just obtain a linear equation slope somehow to estimate the tangent</p>
<p>I know that but what if you use the regression line in all of the other parts?</p>
<p>You get full credit (for those sections where you need an earlier answer) if you use wrong answer(s) from previous parts correctly.</p>
<p>unless your previous answer is completely wrong... You can't make stuff up out of nowhere.</p>
<p>Yes you can. If you don't know the answer to a, simply make up a number that could work, like 1 or e, and use that made-up number to proceed with parts b-d.</p>
<p>can you post a direct link to thesesuper helpful commentaries you're talking about, i still dont see any</p>
<p>I don't think that works dualityim... I tried that on my practice exam and my teacher said you have to show every step how you arrived at the wrong answer for it to work, and it must be reasonable.</p>

<p>That is perfectly fine to make up a number. You won't get the credit for the number nor arriving to it, but you can use it in others parts correctly for full credit (assuming the number is plausible; e.g. if in part a on a physics exam you need to find acceleration which is needed for part b, if you make up 10^100 m/s^2 you won't get credit even for correctly using it)</p>
<p>oh, the time i spent on waiting for my calculator to plot the graph was surging my adrenaline badly (actually killing me). and i almost broke into laughter when a survey question after the MC part B asked how much time i spent on my calculator during the test!</p>
<p>I hate Taylor!!! [I’m okay with the polar stuff]</p>
<p>I love Taylor. My teacher is (sort of) Scottish, so she likes Taylor and MacLaurin.</p>
<p>Posted this over there but got no response…
“did anyone see Jenovo’s post a while back with this practice test?

This is a Collegeboard official practice test…and most of our class failed. Please someone tell me this is harder than actual?”</p>
