Community College to UPenn?

<p>My high-school grades suck. They're decent but definitely not for Ivy League.</p>

<p>I'm starting on a clean slate. I need advices on what I must do in general (ECs, courses to take, community service, GPA) to get into UPenn -Wharton? What are my chances? Am I aiming too high?</p>

<p>This is my first semester in a community college. Right now is a good time to start asking so I know what to do or if I should even bother to try.</p>

<p>Also, can I retake my SATs? Will UPenn allow me to?</p>

<p>I'd love to hear stories of those who transferred from a community college to boost my confidence a little.
I need as much help as I can get so please, help!</p>
