What are my chances for an appeal to USC?

<p>Hey guys, I am relatively new to this site and no one has seemed to help me out so far.</p>

<p>I got rejected from USC yesterday as a transfer student and i was a little bit shocked.</p>

<p>Most of my credits are from a 4 yr in NYC (Pace University). I did this spring semester at a CC due to family issues (i had to come back home in Socal). My friend who also went to pace university got in as a transfer student with the same stats as I have. </p>

<p>My overall gpa is at 3.4, Political Science
I took 21 units this spring semester alone, and taking 11 summer units. so its been crazy!!
This spring semester i got a 3.53. Do you think they will consider these grades?? </p>

<p>Additionally, Im working with the UN as a Young Global Leader, Ive volunteered on a presidential campaign, Ive been on trips to help people with HIV/AIDS in Africa, and this summer I'm helping another aid mission trip to Cuba. I mean what more do they want from me?! </p>

<p>What do you guys suggest I do for my appeal? What are my chances to get in? </p>

<p>Thank you!!!!</p>
