<p>Maybee…But I don’t remember the question.</p>
<p>You know, we should start a consolidated list!!!</p>
<p>Definitely agreed. CaCO3 was assumed to be the only reactant to produce a gas. You can rule out C and D because both are contradictory to the data (some substances actually had CaCO3 in them where as some didn’t; D, I believe, said they were 100% CaCO3 or something like that)</p>
<p>dsus, thats what I put all of CaCO3 had to be the same. The last question for that question I put B about mixing product X and sh** like that. Does anyone agree.</p>
<p>I know that I am new but I /think/ that you had to use some AP Physics Kinematics for the last question on the science section. I believe that you have to consider velocity to the east to be in the positive X direction and velocity pointed to the west to be in the negative X direction – as you know Velocity is a Vector quantity so both the magnitude of the speed AND the direction have to be considered. As a result, I believe that the answer was either toward and toward or away and away (I can’t remember).</p>
<p>I consider myself to be very good at math and science (I am in AP Physics B) and have taken NUMEROUS practice ACT tests prior to this; however, this science section was excruciatingly long… I usually get like 34s but I likely got around a 24 on this one tbh… I know I aced the other three sections, which were all very easy, but science will likely cause me to take this test again in February. Looks like I just need to focus on Science. They need to change these tests so that outside information is NOT required…</p>
<p>Anyways, sorry for the rhetoric…</p>
<p>Any curve predictions?</p>
<p>How are the curves determined prior to exam distribution?</p>
<p>RedAlert, you don’t need any outside information though. The passage specifically tells you that a positive velocity for Vab means a and b are going away from each other, whereas a negative velocity for Vab means a and b are coming closer. That was simply in the passage, so no need to apply kinematic equations. Also, it seems the CC consensus is that it was either away and toward or toward and away. The answer was simply gotten by looking at the relevant table.</p>
<p>dsus, i remember that question clearly and its away and toward, cuz i grossed out toward and away by simply looking at the second column on the table.</p>
<p>CaCO3 was assumed to be the only reactant to produce a gas.</p>
<p>^ I put that and I hope it’s right!</p>
<p>For the one about X and Y, I put that X had a greater whatever because it had a larger percentage of…yeah. I can’t remember the details, but something along those lines.</p>
<p>again, does anyone know what letter -4 was? That was the single question I didn’t have time to read properly and I’m hoping the offchance that I managed to random guess it.</p>
<p>I think it was A?</p>
<p>son of a-</p>
<p>I wish I had at least asked the test proctor to put up the start and end times. I started looking at that question with 30 seconds left, and maybe if I’d managed my time better…</p>
<p>For the CaCO3 prediction thing, were you supposed to look at the percent CaCO3 by mass? or was there some absolute measure of the amount of CaCO3 in the table?</p>
<p>I thought it was also less vegetation=More erosion; but the cars section really tripped me up… aside from that though it wasn’t too bad…I hope -___-</p>
<p>Why didn’t your proctor put up the times…I thought it was mandatory, I’ve never had a proctor not post times and tell you when you had 20 min and 5 mins left…</p>
<p>I took it twice so far. The first time the proctor didn’t put the times up and I had a bad angle to look at the clock. This time the proctor thankfully put up the times and we had a digital clock. I suppose you could ask if the proctor doesn’t put up the start and end times.</p>
<p>I just brought a watch and noted the start/end times on my own. ACT does not even require for rooms to have clocks, so I doubt they would require proctors to put up times. still, every proctor is required to give you a 5 minute warning. that should be sufficient if you have good test strategy IMO</p>
<p>I did the same as @dsus, which was smart on my part because my proctor didn’t give any 5 min warnings and there wasn’t a visible clock from my seat…</p>
<p>Somewhere, good thing you did. I’m extremely surprised your proctor didn’t give 5 minute warnings – I’m almost positive it’s a requirement.</p>
<p>when I first arrived I was under the impression that they allowed us to use our own timers on watches, and the proctor initially said it was okay. Eventually during instructions she read the exact opposite of that, so we thankfully figured out beforehand that I should just use my watch without the timer to avoid disqualification. phew</p>
<p>what were the choices in the CaCo gas one. I mightve guessed right
CACO and one other passage were tough for me. Alleles wer ez.</p>
