<p>I remember that there was a site of past/practice AMC12 problems, but I can't find it by Google, so does anyone have the site of the problems?</p>
<p>Or GO Kalva.......</p>

<p>great site for AIME problems, too</p>
<p>also, if you want to go hardcore,
join <a href="http://www.artofproblemsolving.com%5B/url%5D">www.artofproblemsolving.com</a></p>
<p>how long does the AIME last and how can you get to take it.</p>
<p>It lasts 3 hours. And you have to be in the top 5% of all AMC 12 scorers (100 out of 150), or the top 1% of all AMC 10 scorers (120 out of 150) to take it.</p>
<p>There's also a whole bunch at the amc website, <a href="http://www.unl.edu/amc%5B/url%5D">www.unl.edu/amc</a></p>
