Times are different these days. In the past, hardwork and determination will get you far and somewhere. These days, while these can help, there are things like credentials and educational degrees that one needs to think of. It really is all about how much educational background attainment you can earn so that you can prove that you are “right” for the job. While these days, masteral programs have GMAT (Graduate Management Admission Test) to filter the best and qualified. That is why there are GMAT prep courses one can take, like Knewton’s.
