i'm an international student that will be applying for this cycle. my overall gpa is around 3.75, science gpa is around 3.65. i've done extracurriculars, but most are not related to dentistry. i have around 60 hours of shadowing. i still haven't taken my DAT. i'm wondering what is a safe score in order to ensure an acceptance into any of the 4 schools (Penn, NYU, Columbia, USC) ill be applying to?
