Undergrad Major Questions

<p>Hey guys, I just had a few questions regarding my undergrad major.</p>

<ol>
<li><p>I'm considering double majoring since I have enough credits coming in to do so, is this advisable since it would mean a larger number of upper level classes with the potential to drop my GPA?</p></li>
<li><p>I'm interested primarily in three areas (philosophy, econ, and polisci/IR), should I avoid econ as a major if I'm not particularly good or interested in math? (4 on ap calc, not planning on taking calc 2)</p></li>
</ol>

<p>Thanks guys!</p>
