Official Math IIC January 2005

<p>Hope everyone did great today!</p>

<p>haha...oops, I just noticed that you can't actually discuss the test till noon....</p>

<p>Bah. I didn't do too well on it. Waiting for noon to discuss a few specific problems that are bugging the hell out of me...</p>

<p>Gah i think i did really bad. i left 7 blank. gahh and yesterday i took the Real SAT II practice test and got an 800.......>< >< ><</p>

<p>im so depressed</p>

<p>I don't think I did great either. I left about 5 blank, and had a number of guesses. I'm hoping I can still manage to get over a 700 though.</p>

<p>I finished all the problems, but I didn't have time to check all of them. Of the ones I did check, I made many many errors, so I'm getting worried here. :(</p>

<p>how does ETS decide the curve?</p>

<p>ahhh...I left about two blank, but I think I made a bunch of stupid mistakes...</p>

<p>5 blank. If I got all of the others ones right :rolleyes: I might get an 800. Fat chance of that, though...</p>

<p>hmm...I wonder if we can discuss the questions yet?</p>

<p>it wasnt so bad...i was practicing with barrons during the car ride to the test center lol and that freaked me out a bit but the test overall was a cinch compared to my precalc class....i left .. 2 blank and guessed on 1 or 2. unless i got tricked like 10 times i think i did alright</p>

<p>word on the street is that u can get about 5 or 6 wrong and still get an 800 right?</p>

<p>haha...word on the street...yeah, the curve is that generous</p>

<p>It's 12:06 EST so I think we can discuss questions now</p>

<p>I didn't know there was Calculus on the test. I had to do volume of revolution once and Le'hospital's rule once. Actually, I don't think I needed to use it, but it gave me the right answer, so oh well.</p>

<p>i think on that one...you just get the volume of a cone...</p>

<p>um, yeah. rotating around the x axis formed a cone, and the radius and height were given.</p>

<p>i feel really stupid now, i left like 4 questions blank, and they were ones that i could've done. i left the ln x = e^-x one blank, cuz i didnt understand what it was asking. i left the standard deviation one blank b/c i forgot how to do that. i left the log2 x^2 + 2x one blank because i forgot how to do that too...</p>

<p>2/(3sin^2(x)+2) is undefined at 3.87?</p>

<p>i think so, for that one i just graphed it</p>

<p>what was the last one ... that's the only one I didn't know ... it was either 5 or 8 ....</p>
