Hi Priya650,
Until you have an Official GMAT Score, there will likely be a limit to how accurately anyone will be able to assess your chances of getting accepted to a particular School/Program. In addition, while some Programs will accept applicants with little (or no) Work Experience, most Schools expect applicants to have several years of quality Work Experience (with leadership roles) when those applicants apply.
You're ultimately asking Admissions questions, so you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement.
There's a Forum full of those Experts here:
