<p>Hey everyone! </p>
<p>I'm a Canadian, so I'll be prepping for CCO, but how are you all preparing?</p>
<p>Any advice/suggestions from past participants?</p>
<p>Thanks! :D</p>
<p>I can’t decide whether to prep for USNCO or USAPhO or both, but if I do, I’ll probably be using Atkins</p>
<p>I don’t have enough physics knowledge, so I’m focusing on Chem. </p>
<p>I heard Atkins is really difficult…I own a copy of Chemistry: The Central Science with Brown, LeMay etc. </p>
<p>I heard doing lots of practice tests is the way to go, so i’ll be doing those, I guess</p>
<p>Guys I’m just wondering what is USNCO?</p>
<p>Oh and how can you guys enter it?</p>
<p>Assuming you’re a US citizen, this site should help

<p>Hey guys,</p>
<p>I’m looking to take the USNCO for the first time this year as well, and hoping to at least make semis. I bought a copy of Atkins, but I’m having trouble understanding it since I have only taken honors and not AP. Do you think the studying of Zumdahl would be enough to pass the local exam? Thanks.</p>
