GMAT scores depends in Unis you wanna join. However its not only a criteria. They look at your experince, academic performance and others. In good schools, to get into MBA, you need to have a good GMAT scores. I have seen some frens not getting into MBAs in big schools although having a good GMAT score. However in medicore state unis, you need to have 500 or 550 +. Higher the score better yo have an opportunity. Lower the GMAT score, you will need to have better GPA and expereince. peace out
