Second Chance?

<p>Hey guys, I have a few questions as a new student to cal that I hope can be answered.</p>

<p>What exactly defines a weeder class? And what classes in bio/chem/physics/math/etc would you consider weeder classes that people would either be better off avoiding or should better prepare for?</p>

<p>Any teachers that you believe students should particularly avoid? Any classes for that matter?</p>

<p>As previous cal students what classes would you have taken instead and what would you have done differently if you had a second chance?</p>

<p>Thanks guys, I just kinda wanted a list of classes/teachers to opt out of or watch out for ahead of time and I hope I don't miss out on some really great classes/activities either.</p>
