What I'm saying is that no one is exempted from taking this exam, all those who want to earn an MBA, must take it, it depends on you how many times you want to take this exam. You can take it once, and do mediocre, or you can study you're ass off the first time and do well, then move to the rest of the college applications, with the tools you need to do well on the gmat.
In my opinion,
MGMAT provides a great deal of resources for you to do well. It does not depend solely on strategies or gimmicks, it shows you how to think of the problem, how to execute, and an exit strategy if you do pass the 30 second mark per question and you don't know how to solve, or have forgotten how to.
I'm sure if you take a poll on how many people have retaken the gmat, most will say more than once, so it's up to you how much you give it your best the first time, so you don't have to retake once again.
In my opinion, if I can score between 690-740 in my first shot, then I can move forward and strengthen my application, through essay's, letters of recommendations, etc. Your application is looked at as a whole, so don't be in a rush to get a crappy score on the exam, and a crappy job on everything else, the GMAT reflects you're predictability on your success on the program, if you can't dedicate time and effort to the GMAT, as everyone does, what makes me think that you're application's, letters of recommendations, and essays, will have such attention to detail in the process?
Reality is that, this takes times. If you must apply to another program that does not require the GMAT, then consider those options, and utilize these 3 months to concentrate on essays, and LOR, and redoing you're resume. You can earn an MS in Finance, other great customized programs without having to take the GMAT.
