GRE scores for English PhD

[nyccat]

I am struggling to get the statement of purpose done for an English PhD program. I was planning on retaking the GRE, but now I wonder if given my time constraints  -  full time job, deadline of the application - I'm better off working on my SOP.

I have a 145 in math, 163 in verbal, and 4.5 in the analytic writing.

The math I am helpless in, but I've been told that they don't care about math. I thought I could do a little better on the verbal and on the writing based on practice tests, but under the pressure of the real exam, this might not be true.

As I mentioned, I am really having a hard time with the SOP. It seems like you have to do so much in such a short space. I was wondering if anyone had advice about that too.

Thank you,
