<p>For those of you who made the semi-finalist level in the USABO from previous years, what was your score on the open exam?</p>
<p>I'd like to know that, too. Also, how long did you guys study for it? I took AP Bio last year, so I'm wondering how much I should study in preparation.</p>
<p>In the last couple years, the cutoff for semifinals has been in the mid-20s, and national finalists generally score in the mid-30s and higher. The tests (and competitors) vary from year to year, so don't put too much weight on past scores.</p>
<p>alright- is there also a guessing penalty? I've been searching the USABO website but I can't find anything about it</p>
<p>That information will be given to your teacher when they receive the test.</p>
