Hi itbhu.chirag,
The process of applying to (and ultimately attending) School will require a big investment of time, money and energy on your part, so you really should make sure that applying to Business School is a necessary step to meet your career goals/needs. There are a variety of factors that go into selecting the Schools that you'll apply to, so here are some other things to consider:
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 Degree 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 don't 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.
