<p>Is it encouraged? No more than any other schools.</p>
<p>Is it possible? Certainly, if you go about it intelligently.</p>
<p>I don’t know if you’re in the same situation, but I personally practically have to double major if I’m not to have an exceedingly boring four years due to AP classes. </p>
<p>But in any case, if you research into what classes and requirements there are, I’m sure you won’t find double majoring all that strenuous.</p>
<p>It’s more encouraged than it is at the private schools, certainly, since Berkeley’s breadth requirements (equivalent to private school Core classes) are quite easily fulfilled with your major requirements. Unless you want to toss most of your social life away (I don’t know about Duke specifically, but generally for private schools), double majoring in a private school is not the most prudent course of action.</p>
