Beat The GMAT a GMAT & MBA community

Hi guys,

I recently gave the GMAT. Got a really bad 670(M47,V35). I have targeted Harvard, Northwestern and Stanford. I know that the scores are pretty weak and will take a retest. I am currently doing my graduation as well as I am working full time as a marketing executive. By the time I will complete my grads I will have some 2 Years of work ex. Should I wait after my grads for another 2 to 3 Years or should i apply. And also my GPA will also not be so great.
