Even if you're not in undergrad, you can probably still contact your undergrad school and see if their pre-law advisors are willing to help you. That's what I did, and mine has been incredibly helpful!
Don't worry too much. I know not worrying goes against our usual natures as pre-law students, but it's going to be ok. And there are other avenues like transferring and waitlists. Keep hopeful.
Hey I just wanted to bump this. According to a contact one pre-law advisor has in Georgetown's admissions office, historically 75% of applicants who were offered an individual interview were admitted. FYI.
