I am 34 years old and have a bachelors in math from about 10 years ago. Ive also taken 3 graduate physics courses throughout the years. I work full time as a systems analyst, and have been doing this type of work since I graduated from college in 2005. I also have an MBA. I’m wondering, with my background and age, what are the chances of getting into an Astronomy phd program with just a great PGRE score? I don’t mind leaving my current job and salary if admitted since ultimately my dream is to become an astronomy professor and researcher. I also do not mind going overseas if an overseas school was to admit me (currently I am in California).
