December 2010 ACT Math Discussion

<p>Oh well I’m sure there are many many lurkers out there who are doing the same thing :slight_smile:
I took a nap earlier and woke up because I had a nightmare about an ACT related act of violence (I was walking down a dark alley when a man came and stabbed me with an ACT booklet)</p>

<p>this test is going to mess with me for a while : ]</p>

<p>Yeah, the board is a nice consolidation. I don’t need to worry for hours about how well I did. (It’s a shame, there’s so little time to check answers that I’m 75% sure that I’m 100% right for 90% of the questions. Although I get more answers correct than 75%, it’s hard not to worry that you got them wrong when it’s you only read easy questions once and solve it once. </p>

<p>It’s funny, I was speaking with some of the other calculus students at my school who took the test today that claim to have done poorly (they’re all pessimistic though, I’m sure they were all in the 30’s), but they also wish that this test would have, if anything, pre-calculus questions on it. I too shared this philosophy… until I took the math II SAT subject test. Haha, after taking that last week, I’m glad that the ACT is configured this way. :)</p>

<p>Well, there’s my tangent post for today. To keep it relevant to this test, do you guys think that there was a lack of difficult trig functions? There were no law of sine or cosine problems, and mostly right angle trig questions. (With the exception of the trig identity on the final page.)</p>

<p>Thank goodness there wasn’t a lot of trig :confused: It’s been a while since precalc
Was it just me or did y’all think the last 8-10 were super easy but the 5 before that were >: O type questions? </p>

<p>How many do you guys think would be the most you could get wrong and still get a 33? (I’m very bad at predicting these scores) ~</p>

<p>Does someone remember the pressure problem word for word or close to it because I remember it being easy but I also don’t remember it being E :(</p>

<p>I thought that also Rouxbo. Knowing my habitual errors, I did the last 10 math question in most of the math tests that I could find (3 barron’s + I think 4-6 Princeton Review). Perhaps this prepared me for the last ten questions, or perhaps they were just easy. I remember that I solved the last question in probably less than a minute. (Plugged in 3 for one variable, 4 for the other; found the answer very quickly after logically eliminating about 2 choices then plugging in the rest.) </p>

<p>After checking my answers, I didn’t get the trig question right. (I also didn’t get the rhombus question right, darned geometry. I found the hypotenuse with the Pythagorean’s theorum for both sides then multiplied them.) The trig question really wasn’t hard though, I was just caught up in the wording of the problem. I tried to manipulate the equation by several means… none of which were dividing by cos(x). :P</p>

<p>EDIT: The raw score for a 33 is 55/60. ((55*60)/36) according to the practice book that I got. I’m not sure how the curve will be for this test, but probably worse than 55/60, I’d say maybe 56 or 57 for a 33.</p>

<p>Oh dear =__=;; oh well… I will hope that I did not make any stupid mistakes… but I will… and I will be sad.</p>

<p>^ Yeah I usually make horrific errors in the last 5 and the first 5 :slight_smile: due to nerves + lack of energy? </p>

<p>It was something along the lines of

  1. B decreased slower than A
  2. B increased slower than A
  3. A had a lower minimum pressure than B</p>

<p>I had no idea on this one so I guessed C … none of them seemed to work out for me</p>

<p>I’m afraid I misread it and thought B had a lower minimum :(</p>

<p>I put A because I was nervous about time and it looked good. The answer was E. A looked good because everything about it was correct except that A should have been lower than B.</p>

<p>Oh no, I’m sorry. =\ I don’t remember what the graph of E was, but I think I put this:</p>

<p>QW
ER
T</p>

<p>If the graphs were arranged like that, I think that I put R. It’s hard to say though if that was the correct graph, because it’s only whatever letter choice was right there. I don’t see where I’d have gone wrong though, A was the minimum, B had a less negative slope when decreasing then a less positive slope when increasing. It doesn’t seem like a terribly hard problem, unless the wording sounds was off, but I don’t think that R in my diagram is generally E, which I speculate is normally T? Does anyone know?</p>

<p>^ Yeah, your “R” was choice “E”.</p>

<p>R was E in your diagram. You’re good :)</p>

<p>I’m pretty sure it went
A B
C D
E</p>

<p>It went</p>

<p>AD
BE
C</p>

<p>I have an incredible memory when it comes to stuff like that.</p>

<p>

Uh, no.
A D
B E
C</p>

<p>Oops sorry my bad o:
(it’s amazing how yall can remember so well)</p>

<p>Alright, thanks for the assurance. Let’s just hope that I noticed that as well while taking the test. :)</p>

<p>Dudes i know i got all the questions write</p>

<p>Ran out of time!! guessed b for the last row… was that a good choice ?</p>

<p>^erm…no I don’t think</p>

<p>Can someone please start a consolidated list ?</p>
