Admission chances of Biostatistics/Statistics phD with low GPA and 5+ working experience

[RachelK]

Hi, all,

This might be some kind of unusual application.
I've been out of school for more than 5 years, and been a data analyst for that long.
And I got very low under GPA(2.4) but good MS GPA(3.9).
I'm wondering what my chances would be of getting into a phD program,
or where should I aim based on my profile.
Should I retake my GRE (since only 148 in verbal), or should I take a GRE math subject test even it's not required?
Any suggestion would be appreciated, thanks!
