Please let us know your profile in detail, your domain experience, qualification and where have you started to prepare your GMAT from? Are you taking GMAT Classes or have you joined any GMAT Coachings? This information would help me address your concern more specifically.
Below mentioned are the list of best B Schools where you can try your chances:
1. University of Pennsylvania (Wharton)
2. Harvard University
3. University of Chicago (Booth)
4. Northwestern University (Kellogg)
5. Stanford University
6. University of California ( Haas)

Apart from the above there are many other b schools in USA. An average GMAT Score required for all the above b schools ranges from 660-790. I will suggest you to take GMAT assistance from an experienced GMAT instructor or to take online GMAT Classes if you are working and unable to take out enough time to visit a GMAT Coaching centre.
