SAT Range for Fall 2015 Applicants?

I plan on applying early decision to Northeastern. Disregarding everything else in my application, what is the “sweet spot” for SAT Scores? Also, does a certain section matter more than another?
Took it once so far:
750 Math
630 Critical Reading
550 Writing (anomaly, should be 650ish range this June)

Northeastern doesn’t publish stats until the summer at the earliest but here are the stats for enrolled freshmen in Fall 2014:

If you look at the fall 2015 decision thread on CC you will see that a lot of high test score applicants were denied or offered NU In and some with lower test scores were admitted:

Starts around p. 7.

Admissions is holistic.

i like to think writing is the least important especially if you are a STEM major.
accepted early action this year with:
770 math
700 critical reading
610 writing
