Campbell question for USABO

<p>how long does it take to read through all of campbell for you guys? thanks</p>

<p>A long time if you want to retain that information.</p>

<p>Plus multiple readings :o</p>

<p>=P, I'm thinking its something like 2 hours a chapter, so about 100 hours in total(skipping like the last chapter, and the first couple easy ones)</p>

<p>So, to get to nationals, do you only need to do Campbell and Ravens very thoroughly?</p>
