where are you looking to apply? also are you looking into Full time or Part time programs?

I think with 5 years of work exp and a 650-660 on ur GMAT - u got pretty good chances to apply in top 30 b schools as per the FT rankings. Coz the average years of work exp is around 5 years for many B schools. Also 660 is an average schools for most of the B schools
have a look at the rankings and then the particular websites and the statistics to get a clear picture

Hope this helps

U surely gonna get good university with a score of 650 plus..Then also try for 700+ ..
