<p>I got scaled my score on Barron’s and got a 780-800… HOWEVER, I got 12 wrong and got raw 70/85 (***, srsly). Would you guys say that I am set for a 750+? </p>
<p>Also, just to make sure: when looking at moles for entropy decrease/increase in a reaction, you only look at the GAS moles, right, not the liquid or solid moles? Thanks!</p>
<p>I have a kind of a dumb question, but if the melting point is “low” does that mean the IMF are very strong? (i.e. it would have a high boiling point, etc.)</p>
<p>@darkmagician Thanks so much! Shall ignore organic reagents (like NaBH4, LiAlH4, and what conditions to reduce alkenes to alkanes and convert halogenoalkanes to nitriles etc.)</p>
<p>I just realised that I don’t understand the difference between molecular speed of gases, velocity and kinetic energy of gases! Since KE = 1/2 mv^2 = 3/2RT shouldn’t mass AND temperature affect both of these? Do larger molecules, uh… maybe CO2 have lower molecular speed/velocity/KE than H2 and when does temperature come in the picture?</p>
<p>Less than 12 hours to go >.< HELP!</p>
<p>@ivoryis: I believe that the questions that apear on the test are very simple. A question will ask you out of all the following molecules, which will have the greatest speed. Then, you just choose the molecule with the lowest molecular weight.</p>
<p>Correct me if I’m wrong.</p>
<p>The Sparknotes tests are BS. The questions are way harder than the actual SAT. Granted, this may be good for some people, many others get nervous when they do poorly on practice tests. I would easily suspect a 50 point difference between Sparknotes test scores and SAT test scores. </p>
<p>Regardless, this test typically asks simple questions. There is no acid base titration (which killed me in AP Chem) or anything nearly as complicated. Study your chem vocab and i’m sure you’ll be fine.</p>
<p>^Yeah… I got like a 580 on a SN test and totally lost confidence. But I think their Math II’s are pretty accurate. Still, their chem tests SUCK!</p>
<p>Everyone ready for cram day today?</p>
<p>Taking 8 practice tests… like a boss. Hopefully my score becomes higher than the 560 Barrons predicted for me.</p>
<p>Aznpride2012, i think Math II is fairly accurate. I finished one of theirs in 40 min and got 48/50, which is pretty much what i expected.</p>
<p>Do you guys think there will be a lot on Quantum numbers on the test?</p>
<p>@llazar: hopefully! ace those in my sleep lmao.</p>
<p>anyways guys i have a tip for u. it has worked out on all my barrons practices. if u ever see a balancing question and they ask u what is the simplest form for the WHOLE reaction not an individual reactant/product always AND ALWAYS look for the 2 answers that are like multiples of each other. like for instance one choice is: 1,3,4,6. another answer choice is 2,6,8,12. instead of working the problem out, choose the 1,3,4,6. it has worked out for me very well.</p>
<p>@lancelot: only look at gas’s for concentration/K stuff otherwise look at gas/l/s all the time. </p>
<p>also there isn’t much entropy in solids/liquids. so um just look for the gas if it asks for the reaction with most entropy.</p>
<p>ALSO: should we know Face Centered Cubic stuff?</p>
<p>I have a kind of a dumb question, but if the melting point is “low” does that mean the IMF are very strong? (i.e. it would have a high boiling point, etc.)</p>
<p>This is a total noob question, and I apologize if it’s been mentioned somewhere (no time to look through the entire thread… must cram), but how does the scoring for TTCE work? I know that if you miss one part, the entire question is wrong. So does this mean that if I don’t know the answer to 1 of the 3 parts, I’m better off skipping it entirely? </p>
<p>@girlrockingguna No, if the melting point is low, the IMF are weak. It takes less energy to overcome the IMF, so the melting point is lower.</p>
<p>^If you miss one part, you miss it all. Better to skip it if you know one part, but not the other. </p>
<p>I did only the diagnostic test in Barron’s. I did all three PR tests today and they weren’t that bad, but I still got 70/85 on average. I really want an 800, though. :(</p>
<p>Does anyone have a link to how it’s really graded? What’s the most we can omit to get an 800?</p>
<p>check the actual website. they should have some type of curve up there.</p>
<p>i haven’t checked it yet. maybe later tonight.</p>
<p>The number of people thinking that this test is anywhere near the difficulty of the AP Chemistry test is astonishing! In my opinion it is dramatically easier (and one would expect it to be, considering it does not require a special course). I’m feeling very well prepared, but I’m taking a few more practice tests today because my in-class rival got an 800 on the May one and I would be overjoyed to get an 800 as well.</p>
<p>I took the Kaplan diagnostic test (from the 2002-2003 or whatever book because it was all they had at the library) and got a 790, and the first Sparknotes one and got a 760, but on each one they were mostly careless errors. Hopefully I can get an 800 tomorrow!</p>
<p>Also, if anyone needs any help with the material, I’d be happy to explain anything.</p>
<p>If anyone could explain the experiment described in Barron’s first practice test (48-52) i would greatly appreciate it.</p>
<p>so are the sparknotes tests actually harder than the regular tests?</p>
<p>cause i did really bad on it…
:((hit low 600s…)</p>
<p>i thought the sparknotes were really hard…i scored low 600s on all 3 sparknotes as well, but i scored 770 barrons and 730,770,720 on the 3PR tests</p>
<p>how hard are the PR practice tests compared to the real thing?</p>
