Hi suganyam,
The process of applying to (and ultimately attending) Business School will require a big investment of time, money and energy on your part, so you really should make sure that the Programs that you apply to match your career goals/needs. There are a variety of factors that go into selecting the Schools that you'll apply to. Instead of just applying to Programs in which you might have a good chance to 'get in' (based on your GMAT Score), here are some other things to think about:
1) Is there a particular company that you want to work for or industry that you want to work in? Certain degrees are more appropriate than others if you have a specific career goal.
2) What do you want your MBA to do for you?
3) Do you want to go to School full-time or part-time?
4) Are you willing to relocate? Are you comfortable with working through a program that is primarily online?
5) Are you going to be applying for scholarships?
Etc.
It's okay if you do not have answers to any of these questions just yet, but you really should try to define all of the important variables in terms of your goals, so that you can tailor your entire approach to getting into the best School that matches what you're looking for.
From your last post, it's not clear WHEN you took your practice exams? How long has it been since you took a FULL practice CAT (with all 4 sections - including the Essay and IR sections)? If it has been at least 1 month, then you should plan to take a new practice CAT/mock sometime soon. Make sure to take it in a realistic fashion (take the FULL CAT - with the Essay and IR sections, take it away from your home, at the same time of day as when you'll take the Official GMAT, etc.). Once you have that score, you should report back here and we can discuss how best to proceed.
GMAT assassins aren't born, they're made,
