<p>Thanks HarveyMuddLove.</p>
<p>Is there a difference between the 7th and 8th editions of “Chemistry” by Steven S. Zumdahl, Susan A. Zumdahl. </p>
<p>On Amazon both are priced in the $200 range.</p>
<p>Do students who did not reach the honors level find out their scores? My homeschooled freshman advanced to the National round, and he had to register with a neighboring school system in order to compete. I really appreciate the teacher filing the paperwork for him, and I don’t want to bother him about scores if only the top 150 receive any type of follow-up information.</p>
<p>No one gets any scores. The only way you could know what you got on your MC is if you wrote all the answers on the testing booklet. (then you can compare your answers with the answer key online). They only give you those back, not your Scantron or score. There’s no way to tell what you got on the lab or free response though.</p>
<p>Thanks for the info.</p>

<p>In collaboration with Art of Problem Solving, IChO medalists Brian Lee, Jacob Sanders, and Alex Siegenfeld have created ChemWOOT, an online training program for the US and International Chemistry Olympiads.</p>
<p>The full program description can be found online at
<a href=“http://www.artofproblemsolving.com/School/chemwoot.php?”>http://www.artofproblemsolving.com/School/chemwoot.php?</a> The program includes lectures delivered via online classroom and lots of chemistry practice in the form of problem sets and mock olympiads.</p>
<p>ChemWOOT is aimed at students with a solid AP chemistry background - no previous chemistry olympiad experience necessary.</p>
<p>Bumping this thread for a quick question since I’m pretty sure I made it to this round.</p>
<p>I have been study chemistry out of the Chang 9th edition book. It is what’s used in my AP class, and I have found it to explain almost everything very well. It could go a bit more in depth in organic chemistry, but other than that I have not been surprised by what I’ve seen in the past exams. However, almost everyone touts the Atkins book as the best book available. Is it a good purchase for the USNCO exam, or should I only get it if I make it to the camp?</p>
