<p>I saw that its [#right - .25#wrong]*1.2 + (FRQ points, each question is worth 9] which equals 108 total, 54 each section.</p>
<p>I am certain that the max score for BC is 108. Same scoring procedures as AB, which PKWsurf21 is showing. A 5 for BC is 65-70, similar to AB.</p>
<p>How is partial credit? I did a lot of frq parts right except for one little error, but the work (other than the error) is right. Would I get some credit or is the whole thing wrong because of one error in a step?</p>
<p>it kind of depends. If that subquestion is like worth one point, then you would totally lose that point. But if it’s more than one point, then you would probably receive some points for the work and zero on your incorrect answer.</p>
<p>Question: If I answer a question where it says to find the answer and explain, would i receive the points for the explanation or justification despite the incorrect answer?</p>
<p>Probably. I’ve seen some of the grading rubrics they give the graders. Usually it’s like a point for the answer, and a point or two for the justification.</p>
<p>So, if I have the wrong answer, I would still receive points on justification.</p>

<p>points of inflection can be at places where the slope in undefined as long as the f"(x) changes from positive to negative. and f’(x) is continuous.</p>
<p>You can almost never get the justification point for the wrong answer, unless the wrong answer is the direct result of calculations that are correct based off of a wrong result from a previous part of the question.</p>
<p>That’s wrong. If you miswrote the answer (2+3 = 6 or something), you’ll almost certainly still get the justification points unless you also screwed that up.</p>
<p>guys post up the probelms that you remember</p>
<p>i remember one about a tea question on the MCQ, it was about the temperature</p>
<p>and i put the one that had 90(only one choice)</p>
<p>@JDHarms: Questions that you can simply miswrite the answer (2 + 3 = 6 or something) almost never have justification points. And if it’s obvious that you simply “miswrote” the answer, that’s usually a copy error. That’s different than incorrect calculus that proceeds it. (That being said, not all copy errors will necessarily be recognized as such.)</p>
<p>But the rule of thumb generally is that you cannot correctly justify an incorrect response. AP Readers have repeatedly told me this at various AP Seminars that they run that I have attended.</p>
<p>Justification points usually occur in places where you have to justify a minimum or a maximum, an increasing or a decreasing interval, an inflection point, or where you’re dealing with the concavity. When you’re justifying a statement like this, your justifications have to be based on something that’s actually mathematically correct.</p>
<p>For instance, on the 2008 FRQ’s AB #6 ( <a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board; ), suppose that you were working part (c) and didn’t know how to find the second derivative of that function and made a guess that it was f "(x) = (2 - ln x)/x^3. (Because there’s totally a pattern there…) Suppose that this question had asked you to justify your solution.</p>
<p>If you then solved for the inflection point correctly (x = e^2) for the function that you had determined, and justified it correctly, you would have earned the answer point and a justification point had there been one. (Of course, this only works if you make up a function as complicated as the function you were supposed to work with.)</p>
<p>Conversely, suppose that you had actually found the correct second derivative, but found the incorrect value of x (let’s say you copied your friend’s x = e^2). You can’t earn the justification point for saying the second derivative changes signs at x = e^2 because the second derivative doesn’t change signs at x = e^2, it changes signs at x = e^(3/2).</p>
<p>Thanks for clearing that up. I get it now.</p>
<p>So this is my first time posting, and yesterday was my first AP test. ■■■
I actually preferred the FRQ to the MC.
Still hoping for a generous curve.</p>
<p>ugh same here! frq was alot easier than say, the second portion of mc!</p>
<p>reallly? i found all the calc questions easier than the non-calc.</p>
<p>The first free response question was about students riding bicycles to school.
The last subquestion was asking who lives closer to school?</p>
<p>What was the answer? I thought both of their houses were located in same distance from the school</p>
<p>calculate displacement
i forget which, but one lived farther away</p>
<p>Because the first person had to go back to get his calculator, i subtracted that negative area from the total area.
Then, i got the same distance as the second person’s.</p>
<p>^ yeah that makes sense.</p>
