Credit/No credit- Senior Year

<p>Alright, I'm a senior, this is my final semester and I already have finished one major for my BA. I'm working on finishing up my economics degree, and I've applied to a bunch of PhD programs in economics. They're of varying difficulty/"rank" ranging from mildly competitive to top 10. </p>

<p>Almost all of them say that economics grad students need a strong math background (duh) including calc I, II, III (or multivariate, w/e), stats, linear algebra, etc. I have A's in basically every one of those courses, except the ones I have yet to take. </p>

<p>This upcoming semester I'm in multivariate calc and differential equations. My question is this: will it look bad to grad schools (keep in mind I sent in my transcripts already) if I credit/no credit these math classes (aka only get assigned a "pass" or "fail" without the courses counting towards my GPA)? </p>

<p>It is distinctly possible with all the other things I have going on that I would not receive an A in one of the classes should I not take this option. Is it worth it? </p>

<p>Thanks to anyone who can help!</p>
