<p>^ They changed their policy this year. There aren’t any more deductions for wrong answers!</p>
<p>What would a 37/45 MC and like 29 points on the frq equate to most likely?</p>
<p>Do they really send a letter in the mail if you get 100% on an AP test? I have my fingers crossed!</p>
<p>will colleges look at the AB subscore for the BC exam? what happens if you did bad on the AB subscore but did well overall on the BC exam?</p>
<p>idkwhatnametouse: Ooh, that’s a close one. That would be right on the border between a 4 and a 5.</p>
<p>I think everybody here is underestimating the power of the curve. You only need to get 65% of the test right to get a 5. 65%!</p>
<p>^ that was with the guessing penalty</p>
<p>^From here with the latest test that has curved scores re-fitted to the new no-penalty:</p>
<p>[AP</a> Central - Multiple-Choice Scores](<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)</p>
<p>it’s about 65%…Don’t ruin my hopes for a five haha</p>
<p>For the one with the landfill, what did you get for d^2W/dt^2? I got (1/625)(W-300)…</p>
<p>How exactly does the scoring work? I know the AB Subscore is just the AB topics on the exam but is the BC score just for the BC parts of the exam or the exam as a whole including AB topics?</p>
<p>@kinetix64: I used separation of variables and got a more complex answer… don’t remember haha…</p>
<p>oh and i don’t think im right…btw …</p>
<p>@kinetix i got a different answer than that…i hope i did okay LOL</p>
<p>[AP</a> Pass - AP Calculus Calculator](<a href=“http://appass.com/calculators/calculus]AP”>http://appass.com/calculators/calculus)
i feel like you guys would like this</p>
<p>that makes me feel a lot better.</p>
<p>@kinteics</p>
<p>dW/dt was 1/25(W-300) = W/25 - 12</p>
<p>d2W/dt2 was (dW/dt)/25 - 0 = (W/25 - 12)/25 = W/(25^2) - 12/25 = (1/25)(W/25 - 12) = (1/625)(W-300)</p>
<p>So I got the same answer as you, and if it make you feel any better, I felt confident that I got a raw score of over 90 out of 108 on this test, and that i had the highest GPA in my class all year. And the work is there if you need more reassuring.</p>
<p>I don’t understand that… at all…</p>
<p>Where is your t??? If you derive in terms of t…</p>
<p>^You do implicit differentiation, then plug on dW/dt from the equation originally given. I got the same answer (1/625(W…)) as kinetix and mario.</p>
<p>Kinetix, I got what you got.</p>
<p>For part C, did you guys get…</p>
<p>1100e^(t/25) + 300?</p>
<p>Mikeypz. The embargo’s still up, but let’s just say you aren’t alone :)</p>
<p>A question about the one where you had to find the volume of the rotated exponential equation: was the area rotated about the x-axis or y-axis? I’m afraid I did the wrong one.</p>
