<p>^ Yeah there were a lot of questions requiring outside knowledge-- luckily I think I got most of them. Should this yield a -1 36 curve?</p>
<p>kicking myself for forgetting ohms law… didn’t think i’d need it for the science…</p>
<p>^It told you that something that followed ohm’s law would be constant anyways, and the first two were a constant increase while the diode was exponential. You didn’t really need outside knowledge.</p>
<p>there was barely any outside required knowledge, and the one question that did require it was more vocabulary than science related actually(invasive)</p>
<p>outside knowledge maybe wasnt required, but if one did have outside knowledge they would be able to go through the test much more quickly. Physics is my favorite science, and usually I am unable to finish science on the practice tests. This time, i finished it with 2 minutes to go, so im going to say outside knowledge definitely gave me an advantage.</p>
<p>For that ohms law problem, which answer did you guys select, I cant remember what I had guessed?</p>
<p>Anyone remember this question from the first passage… it was like what percent is not stable or extinct or something like that-- don’t quite remember exactly what it said.</p>
<p>i’m pretty sure it was 65%.</p>
<p>There was way less outside knowledge necessary on this one than the September one. On that one there was an entire section on some weird confusing flower hereditary thing that they didn’t explain. I literally guessed on that entire section but this one was really easy.</p>
<p>i got 65% too</p>
<p>confirmed, 65%</p>
<p>^ Thanks guys</p>
<p>Was it <em>not</em> pyruvic acid (or whatever the acid was) because the pH was less at the halfway point? That’s what I put, but I kind of guessed on that. </p>
<p>Can anyone answer/confirm?</p>
<p>^ do you have any more specifics from that question? that one and the equivalence/halfway point confused me.</p>
<p>^I don’t remember what I said for that, but I do remember that my justification for my answer was that the pH was less than the halfway (not equivalence) point</p>
<p>agreed with somewhere2017</p>
<p>I put half-way point, because in the text it specifically stated that at the half-way point, the pKa should be equal to the PH value (if it’s a neutral solution).</p>
<p>yeah, the science was alot harder than all the real act prep tests! i managed to guess my way through them so fingers crossed
i put halfway point (guessed) and for ohm’s law, i chose the two that weren’t the diode</p>
<p>Too many questions required outside-knowledge as opposed to testing reasoning. The air resistance question, the genus question, the invasive species…unexpected.</p>
<p>That’s exactly what I was thinking Hazy! I got the genus question wrong because I had absolutely no idea what a genus was! I got the air resistance question wrong even though I’m taking honors physics right now. We are covering objects in freefall and the impact air resistance/gravity has on them right now. I narrowed down the answers to those two and just took a guess, which was evidently the wrong one. The invasive species question wasn’t as hard, but outside info would’ve helped.</p>
