Being a first generation student and an under represented minority will both help a lot in a holistic review. EA admissions are largely very high stat, and your GPA/ACT and APs may not be strong enough for an admission on Friday. I do feel like you would do well in a holistic review, particularly if you are not from a highly populated area.
Given the jump of 21% in application numbers for EA, the admissions office has warned applicants to be prepared for a deferral. If you do get deferred, I think a holistic review will benefit you for March admission. Good luck!
