Official Sat Math Level 2 Thread

<p>yaaaaaaayyyyyyyy</p>

<p>edited.... will post on time</p>

<p>I dont think we can discuss this yet. So lets not.</p>

<p>i always run out of time!!</p>

<p>7 blank? what do you think i can get</p>

<p>i hear people thought todays math2c was "insanely easy" if that amkes a difference...</p>

<p>i want an 800 :-(</p>

<p>edit response to user above: i think you can still answer my question though, its only concerning curves and difficulty, not actual test q's</p>

<p>i thought it was easier than the one i took in june, but i still rushed and probably got a load wrong for careless errors. when can we start discussing actual problems?</p>

<p>Anyone who took the test already and wants to talk about it post your AIM</p>

<p>no please don't, keep discussion in here so we can easily read it whenever we want to later on even days from now wehreas an AIM log will be lost</p>

<p>Jks, that will happen anyway.
Who are you to tell me or others what to do? If someone wants to discuss it on AIM they can if they want.</p>

<p>edit: lets begin posting when the california students have begun and have nearly finished the test... at 12:00.</p>

<p>im nto telling you anything, im advising others to discuss in the forum rather than on AIM</p>

<p>it's a legitimate concern - there was like an AIM chatroom for the SAT2 chem last june, and a majority of the discussion was in there so if you werent in the you couldnt really evaluate your performance on the test if you werent in teh chat since there was no record of it.</p>

<p>Because that was so clear from your post...</p>

<p>Edit: Alright, that's fine, but that first comment in itself was irritating. Whatever, it's cool. Hopefully we will be able to remember everything then.</p>

<p>lets all be nice, shall we?</p>

<p>I found the first 30-35 questions incredibly easy, and breezed through them. But I ended up leaving 6 blank...I'll be happy with a 700.</p>

<p>The first 35 questions were quite easy, I got to question 36 and a little over 30 minutes still remained. Then I found some questions that were quite hard for me, I left 4 blank, guessed on 3 and I probably got around 3 wrong for careless mistakes... meh...</p>

<p>Honestly I think we can start posting now.. There is nobody that will be able to benefit from this compilation; all the california kids are already in the midst of their test. Nobody else will be taking it and we havent been warned otherwise...</p>

<p>I hope this isn't too early:</p>

<p>The question about the line perpendicular to the plane: When it asks for the set of points 4 units from the line and 5 units from the plane, it seems like the answer would be one circle. However, that wasn't even an answer choice.</p>

<p>I feel like I did well on this test, except for that question above (which I omitted). Anyone know?</p>

<p>"Well, the second to last (I think) question confused me so much, the one about a bowl sort of inside a cylinder. Also, the one about the f - g below the x-axis, :-/.. oh, and the one that was something like 2r=3s=5v=k or something similar. Those 3 made me mess up. And maybe a couple others I can't remember."
- I didnt have time to do the last 3 questions, so cant help you there.
- Since I rushing I decided to ditch the elegant approach and make k = 30 and see which answers worked... so r=15, s=10, v=6.... E worked.</p>

<p>My own questions
- For the composition of function question near the beginning, f(g(x)), where g(x) was 4x and we had to determine f(x)... was the answer something like 1/2x - 2?
- What was the answer to the permutations question with the 10 slot serial number, 5 letters, 5 numbers?</p>

<p>Edit: APM... Draw a plane and a perpendicular line. When I did this problem it seemed to me that the answer would be 4 points. I dont think a circle would work, what was your reasoning?</p>

<p>First of all, I went 5 units up from the intersection. Now, if you draw a circle around this with radius=4, each point on that circle will be 4 units from the line.</p>

<p>Oops. Was there a choice, "2 circles".. then you would do the same thing below the plane.</p>

<p>bowl inside a cylinder was easy...i think. It was to find the surface area right? I just didnt have enough time. </p>

<p>find the surface area of the circle using the given radius. divide it by two.</p>

<p>find the surface area of the cylinder minus area of a circle using given radius. </p>

<p>add together</p>

<p>^^yes the answer was 2 circles.</p>

<p>its actually 2 circles</p>

<p>if u take the set of points 5 units from the plane, you get 2 planes -- one on either side of the original plane. then the points 4 units from the line creates a cylinder around the line. the cylinder crosses the 2 planes and creates 2 circes.</p>
