Even though 1120 in GRE is not a bad score to be admitted in PhD programs, 73 in TOEFL is quite a low score. Most universities require above 88 in TOEFL iBT. Visit admissions page of Universities websites to get detailed information about score required to get admission. Better the GRE score, better the chances of getting funding.

GRE is either ways not a mandatory requirement here. And even if yoiur score is 1120 it will not make a differende. The most important thing in a PHD application is the research proposal and how you portray your application. For further discussion you can contact me at 9819964458
