<p>I made it! Wow, I just took it on a whim.</p>
<p>good job !</p>
<p>Who else here made it? Anyone know what the quarterfinal test is like?</p>
<p>oh man, I miss the link every year. That was sneaky, not linking it from the information page.</p>
<p>the quarterfinal test is E&M. it's usually significantly more difficult than the previous round. Look for previous exams on the website.</p>
<p>Woo! I made it. Anyone know anything about the cutoff or when they'll post the f=ma exam/solutions?</p>
<p>@sleepy: quarter finals is not all e&m. only 1/4 problems was last year. Dif eqs seem fairly prevalent though, if only seperable and x''=-k^2<em>x and x''=k^2</em>x</p>
<p><a href="http://www.aapt.org/physicsteam/2009/upload/F-ma-Exam-Solutions-2009.pdf%5B/url%5D">http://www.aapt.org/physicsteam/2009/upload/F-ma-Exam-Solutions-2009.pdf</a> is the solutions and the exam. I don't know much about the cutoff, but I definitely say that it's below 16.25.</p>
<p>Last year's cutoff was a 13.75.</p>
<p>This year, I got a 14.5 but didn't make it.</p>
<p>I wish I new about this test, I love physics, and I love doing mechanics problems. Oh well I guess next year I can take the preliminary.</p>
