<p>I read half of Chemical Principles and gave up lol. My advice is to spend most of your time solving problems, not reading.</p>

442

<p>When did they release honors information last year?</p>

443

<p>@Sophia7X: Yes, unlike Bio there is very little information in chem ( comparatively) and basically you apply the same concepts in different ways to solve problems. On that note,
from where can you get extra practice problems?</p>

444

<p>The website is under maintenance, could this be it?</p>

445

<p>lol the site’s back up but they haven’t even posted the national exam yet.</p>

446

<p>found it after playing with the url: <a href=“American Chemical Society”>American Chemical Society;

447

<p>After checking with the online answer key, my final score for MC is 48. (Careless mistakes on Freezing point depression and electrochem :frowning: ). My approximate for FR is 70~80 right now. Can someone chance me for top 150/50? Thanks!</p>

448

<p>that answer key that someone made was completely right if anyone was wondering</p>

449

<p>final score mc is 45 do i have any chance for honors?</p>

450

<p>Right now I am at ~42 MC and ~50% on FRQ. Would I make any thing?</p>

451

<p>yea is around 45-48 enough for honors? also sophia…i want some cookies lol</p>

452

<p>Does anyone think the cutoff of 43 might even go up this year?</p>

453

<p>The cutoff depends on how others did so if this year’s test was harder then past years and people on average did worse then the cutoff is lower and vice versa. So how do guys think the test was? I for one thought it was impossible and am pleasantly surprised with how many guesses i got right</p>

454

<p>what books are best to study to make camp or top 50?</p>

455

<p>I heard Atkin’s is the best textbook.</p>

<p>I’m really nervous for top 150 -_-</p>

456

<p>lol so am i…wat mc score are you lookin at?</p>

457

<p>i got 42-43 on MC so im really really borderline. Which atkins book exactly?</p>

458

<p>@Opinion559</p>

<p>I did exercises out of Zumdahl Chemistry. Also Zumdahl’s Chemical Principles has some excellent exercises especially the challenge problems which involve a lot of thinking. Avoid Atkins Chemical Principles! Atkins is riddled with errors and confusion. Like I said, I read half of it and gave up. Waste of time and I’ll admit I did learn some interesting things, it was not worth the several hours it took to read that much, and a lot of the stuff in it were things I already know. Exercises from Atkins Chemical Principles suck, stick with Zumdahl for exercises. Atkins exercises are surprisingly easy and the only things that are worth anything are the calc-based exercises which are really fun to do if you want to see how calc relates to chem. The only reason I read part of Atkins was because a professor let me have his 6th edition copy so why not.</p>

<p>If you HAVE to read some textbook I recommend Linus Pauling’s General Chemistry.
However, it’s a big waste of time IMO to read a general chemistry textbook-- the only textbook you should be reading is an organic textbook if you are aiming for camp. If you have a strong AP chemistry background, all of the non-organic USNCO problems can be answered based on that except for the random trivia, that you just have to know!</p>

<p>Last year I was able to make top 150 (I believe ~50 on MC and ~70% on frq because got slaughtered by question 8 orgo) on essentially past exams and AP chemistry alone + read a bit of Linus Pauling’s General Chemistry. </p>

<p>This year I was able to make camp with half of Klein’s Organic Chemistry (BEST ORGANIC CHEMISTRY TEXTBOOK, in fact, THE greatest textbook I have read in my entire life, fantastic-- everyone should read this) with ~58 MC and ~90-92% FRQ, most of Pauling (lol still haven’t finished reading this and I started last year), and half of Atkins. So as you can see, not much reading. However, I worked over 500 organic exercises and 2000+ general chemistry exercises. Really you should be working problems most of the time, the reading is only a supplement if you have time/interest.</p>

<p>Holy **** i hate waiting how long did it take last year to release honors information sophia or anyone really</p>

460

<p>on the website, it says top 150 will be announced on may 6 (also day of the chem AP) and so far they’ve been on schedule with releasing the national exam (although I had to go fishing for it with the urls)</p>
