Taking an IGETC course P/NP

<p>Hi guys. Well I'm applying for Fall 2010 admission as a sociology major and my top choice is UC Berkeley or UCLA. My GPA is quite good but I am worried about an IGETC-required physical science class w/ lab I took P/NP last year because I had a very busy semester (work and personal issues). Do you think this will hurt my chances at all? Is it worth explaining why I took it P/NP in my application? (I actually ended up with a B in the class but of course they'll never know...) It's the only class I've taken P/NP. </p>

<p>Thanks and gl to everyone applying this year!</p>
