<p>It was much harder than I had anticipated. I studied as much as I could, but some of the questions were over vague topics I didn’t look over in much depth. I omitted 8 or 9, and I’m hoping to god I got the rest right. I really want an 800, but I’d settle for a 750. Let’s hope for a generous curve.</p>
<p>I omitted 4. Fir the one about the universe expanding with I, II, III, I know red light shift was one reason, was there another?</p>
<p>I have no clue. I knew red shift was one, but I didn’t want to guess. Does the focal length of a lens change underwater?</p>
<p>I didn’t know, I left it blank.</p>
<p>I just looked it up. Apparently it does, which means I’m starting with at least a -9 raw score. Oh well.</p>
<p>Anyone know what the physics curve has been in the past?</p>
<p>Usually a -10 to -15 is an 800, i personally thought this test was relatively easier than the practice ones I took. I omitted 7 or 8 and hopefully got no more than 3 or 4 wrong. </p>
<p>For the universe expanding one, i put I and II, III was the elliptical orbit of planets or something and that definitely didn’t sound right, and since I alone was not a choice, and the other choices had III in them, the only remaining choice was I and II. At least, I hope lol</p>
<p>What was the one about the oil drop experiment thing with the charges? </p>
<p>Also, does someone want to start compiling a list once we decide on 3/4 more questions? ;)</p>
<p>PioneerJones, how well did you do on practice tests? I also felt the test was a lot harder than anything I took for practice.
It was -16 raw = 800 in the blue book, but that seems really generous. The sparknotes curve was ~ -12 raw = 800 I think.
I omitted 5, and I missed the focal length one too.</p>
<p>For universe, I think I put redshift and another choice, can’t remember.</p>
<p>In the collegeboard book a raw score of 59 is an 800. That seems really low, but the curve should be somewhere around 60- low 60s.</p>
<p>At the beginning, there was a table with values and it was matching the tables to descriptions.</p>
<p>What did you get for those?</p>
<p>I put something about integers of something. I think the oil drop showed electron energy levels, and that was the most similar.</p>
<p>What was the one about the oil drop experiment thing with the charges?
–it was that the charge is always some multiple of a definite value, choice E if I remember correctly</p>
<p>why is the biology thread so much longer than this one -_-</p>
<p>come on people, start discussing!</p>
<p>I think it was to calculate the charge of the electron? if that was a choice</p>
<p>[Oil</a> drop experiment - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Oil_drop_experiment]Oil”>Oil drop experiment - Wikipedia)</p>
<p>table of values question–what was the one with acceleration? and then another with kinetic energy?</p>
<p>sorry for being so vague. it’s been like 4 hours.</p>
<p>If you read the article farther it mentions multiples, and that’s the answer. I hot it right :)</p>

<p>^^Nice! I left it blank, soo … ^_^</p>
<p>I think this was the graph of the one asking about the temperature of a cube of ice at -50C being heated until it reaches a temperature of 150C. </p>

<p>There was also a question about two blocks, X and Y which collide, going with v1 and v2 respectively. The question was about the value of v1/v2. I think you should have the masses of both objects to find out, don’t you? That was my choice. (think it was E)</p>
<p>The instantaneous velocity with the graph was 0 correct? Since the tangent line at that point had a slope of 0</p>
