Official US December SAT I Thread

<p>ALexmartin, </p>

<p>9*7=63, thus you cannot have 63</p>

<p>alex, the question was something like: which of the following disproves the theory that the odd number after a prime number ending in 1 is prime?</p>

<p>63 isnt prime, its divisble by 3</p>

<p>43 is prime though</p>

<p>I had 3 math sections in-a-row, so I'm certain that I didn't have an experiemental verbal.
Question: I had a quant-comp/grid-in sandwiched between two 30 minute math sections (sections 2, then 4, then 5). The last 30 minute math section was really HARD (I never think that these questions are hard), even the first 5 questions. Every single SAT has to have one grid-in/quant-comp section, right? And they don't make section 2 experimental, do they?</p>

<p>yeh, that's it alex..i can't remember numbers. i think i missed four on math..but i think they were trying to trick some people on the train question...and possibly one or two other questions, so maybe the curve may be 800,790..possibly. verbal should be really nice. i missed about 10-15, i'm looking at like...660-710, math..eh, 710 hopefully.</p>

<p>Yeah, that question asked you to find a counterexample to the statement that f you add 2 to a prime number ending in 1 you will get another prime number. The answer is 61,63</p>

<p>It asked to prove the statement false, not true.</p>

<p>wait, was it? ahhh, can't remember. the only thing i remember is i had to change mai answer because i got it wrong on the first time.</p>

<p>oh, my bad then. i remember thinking through the problem, i hope i put 61/63...</p>

<p>But I saw others that were also composite. Hmm I probably missed it. 2 wrong then :(</p>

<p>yea, that's right.</p>

<p>yeah it was assertive, my "bad"</p>

<p>anyway, yeah reading killed me like always, the last reading was hard. I breezed through the first 7 and stumbled the last 6. I got a lot of D's, like 5 d's of the 13 answers and 3 Es</p>

<p>can someone post the exact numbers on the train question? I got 1000, and at the time I was certain that it was right (then again, I do make bonehead mistakes... I think that I changed my answer from 1200 to 1000, and if I did I'm a moron).</p>

<p>a train 200m long is going at 20 m/s and enters a tunnel, in which it spends 1 min 10 sec. how long is the tunnel?</p>

<p>i got CCC for the answers for the last reading passage</p>

<p>No, it said whats the least in which a prime number is added to another prime</p>

<p>41,43 not 61,63</p>

<p>The time was 1hr 10min, the velocity was 20m/s, and the length of the train was 200 meters.</p>

<p>If anyone had verbal as the first section, did anyone notice only 2-3 A answers</p>

<p>no, it said..prime number, then afterwards..the next odd number, is prime also..which disproves that..it was 61, 63</p>

<p>it is 1200 for sure. 20/s= v, 70s=t, to get distance you have to multiple 20 by 70 and u will get 1400. but then the trick part is you have to subtract 200 (that's how long the train is). i didn't realize the trick part and put 1400 and it's gonna ruin my math score.</p>

<p>Jimmy, </p>

<p>Tunnel is 1200. because you kno S<em>t=d and the time is 70 seconds, speed 20 m/s so we have 20</em>70=1400 and we have to take into account length of train which was 200 so we have 1400-200=1200</p>
