Hi Pooja,
While it might be tempting just to go for a School that is likely to accept you, there are a variety of questions that YOU have to answer about what you want out of an MBA and the parameters that are important to you. You've already mentioned how you want to apply for a Full-time Program, but there are other factors to consider, including:
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) Are you willing to relocate? Are you comfortable with working through a program that is primarily online?
4) Are you going to be applying for scholarships?
Etc.
Once you've determined what type of Program you want to attend (as well as the other variables involved), then you can start to research and narrow down the possibilities.
