<p>^ i found that one a while back… its has Q and answers</p>

<p>does anyone know the curve for apes?</p>

5

<p>anyone wanna explain half life on Q 44? I used proportions,and got 25 yrs, but the answer is 50; am i missing something here?
and Q57, 58( i got 5100MW -.-?)…
they’re all math based, hm quite ironic~
thanks</p>

<p>Thanks a lot for the answers! If you have the answers to these as well, it’ll be even more helpful!</p>

<p>Btw. Here’s how you do #44. If you think about it 1/16 = 1/(2)^4</p>

<p>That means 4 half lifes occurred in 200 years, therefore… 50</p>

7

<p>^ are those real tests??</p>

<p>hm, so half life is
50 mil yrs, 1/2
100 mil yrs, 1/4
200 mil yrs, 1/(?)</p>

<p>so its actually like (1/2)^n ?
my textbook doesn’t explain this =/</p>

8

<p>thank you for this!</p>

<p>Where are the answers on these practice tests?</p>

10

<p>for Ren the Sat’ers link they are just at the bottom…</p>

11

<p>Nevermind my computer took awhile to load the whole thing. By the way, does anyone have an approximate curve for this like what equals 5, 4, etc. Or maybe curves from past years? Thanks</p>

12

<p>according to my Princeton Review book, a composite score of 91 from last year got you a 5… in case you don’t know, its section 1: (number right - (number wrong/4)) + (section 2: total score of four FRQs x 1.5) = composite score so the total would be 150</p>

13

<p>@ REN</p>

<p>It’s like this…</p>

<p>50 million years, 1/2 left
100 million years, 1/4 left
150 million years, 1/8 left
200 million years 1/16 left</p>

<p>Also, I saw that curve in the PR book. Curve seems really generous! However, in both Smarty Pants & REA, they say that it’s out of 160 pts and 120-160 is a 5. However, in their case mc = 62.5% of the test. Any veterans care to explain?</p>

14

<p>heh I hope its the PR one… random question, but is the number of Hydrogen ions in the pH scale exponential? (question 22 i think the 2008 test)</p>

15

<p>Is the one with the asnwers really the 2008 test? Becuase the free response on collegeboard for the 2008 test is different than the ones on that link.</p>

16

<p>^ It is the 2008 Audit Exam, not the 2008 administered exam.</p>

17

<p>Is it bad if this test seems very difficult haha</p>

18

<p>Yea… I started off really well, then I was like OMG… after like 50 questions. lol</p>

<p>If it’s the PR curve, then THANK GOD. If not, I’m screwed…</p>

19

<p>Ya, and I did a practice test from the Princeton Review book and it was easy I got like 80/100. Then that one is wayyy harder…</p>

20

<p>Yeah… Well, I guess you could POE a lot of answers. (That’s what I did)</p>

<p>Still ended up w/ a C on the exam. LOL
I hope Collegeboard goes easy on us on Tuesday.</p>
