GRE Requirements: How Important Are They?

[hatecoffee0h0h]

Hi, 

I'm applying to PhD programs for the Fall 2020 round and I'm worried about GRE requirements. I work two jobs and travel a lot for work and so have not had the time to take the exam.

I know deadlines are fast approaching for when I should take it (most unis ask that prospective students take the GRE before Nov 1), but my local test center has no dates available. My scores from the time I applied to my MA are still valid but they're not very good (150 Q, 153 V, 4.5 AW) and I don't think they reflect my profile as an applicant. So my question is – should I bother taking the GRE after the Nov 1 deadline (the earliest date I could find is Nov 18) or should I just submit the scores I have right now and hope for the best? How important is the GRE really?
