noncore Incoming BB Sponsors analyst -> MM PE chances

I'm currently an incoming analyst at a Financial Sponsors group at CS/Barc/DB/UBS. I go to a non-target school and will graduate with a 3.5 GPA. My SAT scores are really bad as well, would probably omit them from my resume during recruiting. I know my chances of breaking into a reputable MM PE shop are low, I was wondering if anyone knows of someone in a similar situation who it pulled it off.

I would appreciate any input.
