I'm expecting around 315-325 in GRE and will clear TOEFL (90-105). I've got a decent academic record.

I just wanted to know how common is it for someone to get financial aid by the university, and how much do they cover?
Other than that, is there a separate procedure for applying for financial aid, or is it done through the application process itself.
Any information from someone who's been through this would be great.
