A few questions on Boston University

<li><p>Should I apply for Early Decision II? I’ll be taking the ACT + Writing in Dec, instead of the SAT2.</p></li>
<li><p>How important is GPA? Mine is a bit low, and I’m greatly disappointed by it: 3.4, is that GPA too low for Boston?</p></li>
</ol>

<p>But there are reasons why my GPA is low, depression, switching schools and weighted classes becoing unweighted, etc. Will I be able to explain these things?</p>
