<p>Hey guys,</p>
<p>i qualified for the USNCO national test, and i really want to make at least honorable mention, but i have no idea on how to prepare. I heard that the usnco test is more broad, that you have to have a solid base in organic chemistry, and that it's significatnly harder than the local exam.</p>
<p>i know that there are practice tests online, but i still wanna prep for it. which books should i use?</p>
<p>i got a 61/70 on the local exam, (our district adds 10 extra questions) or 57/60 for the first 60 questions. </p>
<p>I really appreciate your help!</p>
