<p>I think I put 160 for the one that some of you are talking about …I was just making an observation on that one, hahaha.</p>
<p>the matrix/factorial problem was just addition of matrices right? then you get a and b and solve?</p>
<p>I was certainly surprised to see that proof as number 59. I like a lot of people got it down to B and D and of course I cannot remember which one I did. -_-</p>
<p>D was SAS! come on guys!</p>
<h1>12 was 3k-20 not 3k+30</h1>
<p>agreed…i think. </p>
<p>has it ever happened before that a -1 on math is a 36?</p>
<p>The question said "what is 20 more than 3 times the speed, whereas K is the speed "</p>
<p>3K+20</p>

<p>your right. i was thinking in terms of an equation: k=3k-20.</p>
<p>Still doesn’t make sense haha but fair enough</p>

<p>yeah i think i remembered a + in there, not a -…</p>

<p>The 2 and 5/12 question was asking you to add 1 2/3 and 3/4 I believe.</p>
<p>I didn’t bother reading through all the pages, but could someone sum up for me the general consensus:</p>
<p>Did everyone else run out of time too!? The proctor called 5 minutes and I had like 12 questions left, I freaked out! Answered the ones that I could do within 30 secs, and “educated guessed” on the rest. By educated guess I just filled what looked right!</p>
<p>■■■, first time taking the ACT and I run out of time. Great. SAT Math section was easier than that crap :/</p>
<p>I got at least 6 or 7 wrong, how generous would the curve be? Do I still have a chance at 30+?</p>
<p>it really depends on the day.</p>
<p>i got almost perfect on one SAT math section, then 2 months later i got over 100 points less on it.</p>
<p>ACT math is generally easier, but then again sometimes theyre good at throwing curveballs at you. generally the problems have shortcuts though. i didnt find the math this time that hard; you just have to pace yourself!</p>
<p>haha dont worry it dosent make sense. and ^ i think it was a bit harder than the last one i took, but missing 8-10 might be around a 30</p>
<p>I sped through the easy questions and had about 25 minutes left for the last two pages, and finished with about five minutes left after spending way too much time on the proof, the polynomial factor, and the matrix questions. This way my first time taking the ACT, and I thought the math was much harder than the SAT Math IIC subject test (which I finished in enough time to go back and recheck each question).</p>
<p>On that 3k + 20 or - 20, mostly just saying this to console myself but the question wasn’t worded in that way exactly I’m pretty sure, cause if it was I wouldn’t have gotten stuck by it. <_< Still wasn’t that difficult of a question and I wish I did more than guess on it but the difficulty in that one was certainly the way it was worded, cause again, would have gotten it if the wording didn’t confuzzle me.</p>
<p>SAT math II wasnt too bad this time around though. do you guys really think the math section today was bad? hahahah. it just threw some curveballs. the polynomial one was simple: synthetic division! the matrix one, wasnt that just adding? and the proof, well, i guess ya just gotta know your geometry theorems!!! :)</p>
<p>Right, about the polynomial one, but I forgot how to do synthetic division so I was working it with long division (and I didn’t realize that -2 was a factor and f(-2) = 0). And for the matrix one, we never actually learned how to add matrices by hand, only on the calculator, but luckily I remembered how to solve them after a bit of trial and error.</p>
<p>dont you just add them in the corresponding spots?</p>
<p>its multiplying them that can get tricky, but im pretty sure it just asked to add the two</p>
<p>Matrix problem was something like:
[3!] + [2!] = a/b
[2!] [4!]</p>
<p>You get ((1<em>2</em>3)+(1<em>2))/((1</em>2)+(1<em>2</em>3*4))</p>
<p>or (6+2)/(2+24), which is 8/26.</p>
<p>Reduce to 4/13 and flip to 13/4 because the problem asked for b/a</p>
<p>I’ve never done matrices before (or I did them briefly without ever really learning them), but the problem tells you how to solve it.</p>
