<p>Anyone have any ideas how to prepare for the upcoming USNCO exam next year?</p>
<p>I know practice tests are quintessential. I'm wondering what preparatory books or textbooks are sufficient for a solid understanding of the material. Would a standard AP Chemistry textbook (Zumdahl) be fine?</p>
<p>Anyone, preferably with experience in the USNCO press, I would appreciate the feedback.</p>
<p>Also, if there are any miscellaneous tips or advice or past experiences with this competition, I would love to know them.</p>
<p>Thanks for your help!</p>
