If, for whatever reason, you are not being accepted with you stats and you attempt, without success, to change them, what is the point?
My advice to someone with a real desire to become an AA but that has been getting rejected is to get some healthcare experience. It, in my opinion, can make up for lower GPA's and GRE scores. Get your EMT certification and work for a year or two and possibly go to grad school at a public university part time to get a health care related graduate certificate or MS. Having that additional experience and graduate education will really build up your application and your CV when you apply for AA jobs after you graduate. Its completely worth the extra year or two of work if you are rejected from AA school and are determined to be an AA.
