<p>nah dont even bother. i knew like half the people in the class this semester and i was in math 25, and the impression that i get is that its hit or miss, that you either can handle it or you cant (in which case people tend to drop down to 25, and they also do that if they just dont wanna spend their lives doing math). so it probably just isnt worth your time to prepare for it.</p>
<p>that said, it seems like none of the psets are online or anything from what i can see.</p>
