Undergraduate / transferring in with 38 previous college hours and a 3.5 from my last semester [3]

Hello, im new to this site but have been looking around at all the forums and have seen how helpful they are! Hopefully someone will be able to help me out the same :)

Im currently a freshman at a community college near Texas A&M. I applied to A&M last year, but was not admitted. I wasnt in the top 10% when I applied, but I managed to make my way into it when I graduated. Anyhow, I have to write a statement of purpose essay as a credential for transfering into the college. The topic is as follows:

The statement of purpose will provide an opportunity to explain any extenuating circumstances that you feel could add value to your application. You may also want to explain unique aspects of your academic background or valued experiences you may have had that relate to your academic discipline. The statement of purpose is not meant to be a listing of accomplishments in high school or a record of your participation in school-related activities. Rather, this is your opportunity to address the admissions committee directly and to let us know more about you as an individual, in a manner that your transcripts and other application information cannot convey.

Im stuck on what exactly to write about. Im transferring in with 38 previous college hours and a 3.5 from my last semester. I know I want to apply to the college of education and human development, department of health and kinesiology, to obtain a b.s in allied health in order to advance to a physician assistant school.

Any and all help is much appreciated! :)
