@sdiaz1924 Hi there!
I'm on the same boat as you, except I'm applying for the PhD programs in Crim&CrimJustice for this upcoming fall 2017 semester. Being from Canada, this is my first time doing a standardized test for university admissions, but based on what I'm reading from these forum threads, the GRE scores can be very important -- especially at the Master's level. Even in Canada, I was told that GPA is really important for admissions in the Master's programs, whereas for the PhD, soft scores such as research experience, fit with faculty, and work experience are weighed more favorably.
That being said, I think a decent score/safe score for the GREs is around the 300-315 mark. Obviously, aim for higher, but if your application is competitive, the GRE shouldn't the breaking factor.
I'm preparing for the GRE myself and will be taking it this November -- I'm going for a one shot wonder, no retakes. I'm also pretty horrendous with standardized testings, but I'm just aiming for the average'ish score of 310-315. Try to email the schools that you're applying to and ask them what the average GRE score is for the students admitted. They should tell you a rough average and also answer any other questions you have.
Good luck my friend! Best of luck! I want to do my PhD at Northeastern as well, so if you get into NE for your MA, that would be super cool!
Cheers!
