I dropped an AP Class, but I haven't been accepted yet. When do I notify CPP?

<p>I dropped out of AP Environmental Science due to a low grade(C-) first semester, as well as a new found interest in an ROP program I joined in school. I’ve completed all of my A-G courses prior to enrolling in APES and I didn’t get any Ds or Fs during my first semester of senior year, so hopefully I don’t run into any problems down the road. Do I notify Cal Poly Pomona of a change in my course list right now or do I have to wait until I actually receive acceptance? How do I do this?</p>

<p>Thanks for the advice, CPP CC!</p>
