UC Admissions- 1st semester grades

<p>okay so I recently got accepted into UCSD like four days ago and I found out that I got two D's in my ap courses and I don't know what to do about it. i wrote them an email about what happened and my reason for getting those grades and I have been talking to my counselors, college offices, assistant principle, etc. and they just said to write to them, but that's all I can do. Is there anything I can do to change it or to help it at least by a little bit?? I didn't get these grades because I was slacking off or procrastinating or anything! It was all due to the rigorous classes that I was taking last semester .. and I HAD to get out of calculus class because the teacher said that he wouldn't give me any credit for 2nd semester if i stayed so there wasn't any point in taking the class anymore =\ My calculus teacher is one of the hardest teachers in our LAUSD district and it was just soo hard for me to stay on top of the class. He gave me many pages of homework to do and on top of that, I had to keep up with my ap physics class. I am also in magnet so I'm taking college philosophy and humanties, etc. It's all have been so hard on me .. plus i work :[ I'M the one that supports my family .. and it's just been so hard. So do you guys think that there's some kind of chance for me out there? I wrote them a two page letter stating what happened and why I got those grades .. UCSD has been my dream school for the longest time i can remember and I finally got in .. and I really don't want to get my admission revoked :[ i worked too hard to get revoked like this. It just sucks to get rejected after I get accepted. ahhh iono please someone, help me!! give me some kind of hope or something T-T ....</p>
