The Application Process

Hello
I completed my BBA with major in finance and accounting from American International University in Bangladesh with a CGPA of 3.78. I have over 7 years of work experience focused on sales management and its different focus. Currently am working in sprint. I want to get back to school for masters in accounting and then complete CPA. My targeted colleges are Baruch, NYU, Fordham, Pace, Stoony Brooks and Yale.
Can you give me a rough idea about how much should I be targetting for in my GMAT.

Also, for masters in accounting, what is the best semester to get enrolled? Is it fall or spring or it doesnt matter?

Thanks and really looking forward to get some feedback on this as I really need some helpful advice.
