Lower Admissions for PEA/ Chance

<p>Hey...
What are the acceptance rates are for PEA and entering as a lower? I applied for financial aid, but I'm a bit dubious about receiving it.
Have really good grades at a rigorous highschool, and did 95th percentile overall on the SSAT felt like I had a good interview and I'm fairly certain I got good reports form teachers (they all like me but nobody can be 100%). Also, I had well written and creative essays. So I guess this is more of a chances thing, but I am really curious about the question above as well.</p>
