Hi there,
I may not be understanding correctly... I thought you say you did a practice test, GMAT Prep 1, and got a 570? so that is not the real test? Hence my comment that you may improve from there...
If you were to apply with a 570, I would look at schools outside the top 50 on US News & World Report rankings (can view that online), maybe Katz in Pittsburgh, Babson, UT Knoxville, Baylor, maybe Boston College though that might be too much of a stretch.... you can see the average GMAT scores and acceptance rates on the US News rankings if useful.
