If it's for Duke, it may be too late. I asked an admissions officer point-blank during an information session and he flat-out told me spots will be full by December.
Congrats on your score! but w/ your goals I would retake! Applied to GULC & Duke with similar gpa and 169 and was waitlisted last cycle, currently retaking and wish id done it sooner tbh!
@canihazJD - is URM on the basis of ethnicity / race still relevant for the application process? Would being a first generation college student entail being a URM (e.g. parent's highest-level being high school)?
