What's the Hardest class you've taken at Columbia?

<p>can someone post some more information (maybe some psets) or something for accelerated physics? It looks interesting but I can’t find too much about it online.</p>

<p>The typical problem is one in which it appears that you need a bunch more information to begin to answer the question and where you need to have some abstract physics skill to figure out some assumption that you need to make to make the problem look easy.</p>
