<p>I got C’s in AP Chemistry and AP Physics B (both 79.6%'s, I got screwed over in Chem, would’ve had a B- but there was a rounding difference). Both classes were much harder than I thought. I heard somewhere that if you get a C (or possibly two C’s) you have to write a letter of justification to the UC’s you applied to (for me, SD, LA, Irvine, Davis). </p>
<p>Is this true? If yes, when should I send these letters and where do I send them?</p>
<p>EDIT: Also crossposted to UC-General, I didn’t realize there was such a forum.</p>
