Hi crack1991,
Given the Schools that you've listed, a higher GMAT score would definitely help your chances (which means that you'll have to make some significant improvements to how you handle the Verbal section of the GMAT). If you're not going to be applying until later on this year, then you have plenty of time to study and improve, which is good.
Since your last Official GMAT was in November, it would be a good idea for you to take a new FULL-LENGTH CAT (with the Essay and IR sections), so we can get a sense of your current skills, strengths and weaknesses. Once you have that score, you should report back here and we can discuss your study plan going forwards.
1) How long did you study before each attempt at the GMAT?
2) What materials did you use for each attempt?
