FWIW, I got accepted to Emory 3 days after I went complete. I am URM though. I dont think you can/should make predictions about what other schools may do based on what Emory did. I do think though, if you go complete this fast, it shows they like you. Maybe they want to increase their science major students for patent bars and stuff.
You just might get some $$, but dont feel bad if you dont. Emory is notoriously tight with the cash. I probably will get money from most of the smiliarly ranked schools I get into, but not Emory, except if its need aid or something.
