Hi MALLEKB,
You're ultimately asking Admissions questions, so you would likely find it beneficial to speak with an Admissions Expert about your overall profile and application plans. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admission ... tants-124/The Average Score on the Official GMAT hovers around 550 most years, so your 570 is just a bit above-average. The Q35 might be an issue, as it's a below-average performance in that section. That having been said, Business Schools know that not every Applicant is a great Test Taker - and there are a number of aspects to the application that you might be able to use to 'make up' for the Q35. If you do choose to retest, then you could potentially focus on the Quant section (including your general math skills and Quant Tactics) and pick up some points in a relatively short period of time (re: a month or so).
1) What application deadlines are you currently facing?
