2011 January SAT: Math

<p>DrillKid,
With a -2 or a -3, there is a good chance you will still be at a 740-750.</p>

<p>UGH I hate math. It has less questions and I miss the most on math. I’ll probably miss more on math than cr/writing combined. Meanwhile everyone on this site is worrying about CR and feeling great about math. I’m the exact opposite. I know the questions were easy but the time limit kills me in math.</p>

<p>Coming from a math-oriented student, I thought that this SAT was very easy except for 1 or 2 problems per section. Did you guys feel the same way? For example, the 50/51 summation problem took me 8 minute…</p>

<p>I still think I got an 800 (If i didn’t make stupid easy mistakes), but the hard questions were challenging.</p>

<p>What was the grid-in question that had the answer 1/3?</p>

<p>Can anyone explain how the regular pentagon problem inscribed in a circle was 10? i thought it asked how many times it touched the circle which would be 5</p>

<p>Mcken, that was experimental, doesn’t matter. ;)</p>

<p>hahah i just drew the pentagons… took me a while.</p>

<p>which question was 16 in the grid in and which one was 1/3?</p>

<p>what u guys estimating curve for -1?
I think something like 780.</p>

<p>@eshift
don’t remember it exactly
but it told you line l went through a certain point, was parallel to another line, and had the form y = ax+b
it asked you to find a+b, which involved calculating -2/3 + 1</p>

<p>so I omitted the sqrt5 -1 and did not get the egg one right for some reason…any possible score range? someone who has taken them before</p>

<p>haven’t taken them before, but it’s reasonable to assume that it’s about a 770, provided you got no another ones wrong
[also depending on the curve - but from what i have seen, the curve won’t be too generous]</p>

<p>wait whoops. wrong problem.</p>

<p>@classic.</p>

<p>Uh oh. I got 0 for that one. I thought I had -2/3 + 2/3 which came out to 0. Do you remember the specific question?</p>

<p>hhaha are you talking about the hexagons one!?
where you had to find the number of total things in the 5th hexagon?</p>

<p>because if so, i give you kudos for drawing them all out…
wow. so much willpower.</p>

<p>how much did you get for the hexagons one? Was it like 91 or 96 or something? It was like 1+6+12+24+48. right?</p>

<p>for the one question it was w^2 to x^2, right? because i had 9/4 but then at the last second switched to 4/9</p>

<p>@presidont:
hmm.
line l: y=ax+b
line l parallel to y = -2/3x + something?
goes through (0, 1) </p>

<p>yeah, something like that.
find a+b</p>

<p>@interficio:
the answer was 61.</p>

<p>if you got 91, i believe you calculated one more hexagon then you were supposed to</p>

<p>basically:
the first had 1
the second had 7
the third had 19
the fourth would have 37
the fifth would have 61.</p>

<p>oh, I understand why I got that wrong. I double each increment instead of adding six… but I just need one more person to confirm that it was 61 and not 91 so I can freak out appropriately. LOL</p>
