Help with an APA style letter to the dean

Below is an edited copy of a letter I recieved while trying to get into grad school. I had a cummulative gpa of 2.51 in undergrad due to a change of major. The requirements to get into the school require me to have a 2.75 for the last 22 classes I took some of which I recieved poor grades and instead of having to retake them I changed my major. My starting major was accounting and I finished with marketing and am currently ironically trying to go to school for a masters in accounting. The problem is I have no idea how to write an apa style letter to the dean or even an apa letter. It has to be one page APA style and answer the following questions below. The only part I left out is the schools name and a recommended review of the schools policies. If someone could point me in the right direction or start a letter given the circumstances and information provided I would really appreciate it as I have only 24 hours to do so. Thanks in advance. Below is the edited letter.

Dear Mr Me,

Your gpa is a 2.51 and you have to have a 2.75 to get into the master's degree program. However, you can still get into this program, but I will need for you to complete the instructions below:

The review of your undergraduate cumulative Grade Point Average (GPA) shows it does not meet the 2.75 GPA requirement for admittance into a graduate program. However, you may provide a letter of explanation, a resume, and transcripts that may explain and reveal evidence of graduate potential for the Academic Dean to review.

I. Compose a letter to the Academic Dean that provides the following:
a. A detailed explanation as to why you feel as though you were not able to earn a higher GPA.
b. A detailed explanation as to what may be different now that will enable you to be successful
and to achieve and maintain a 3.0 or higher.
c. Review and include a statement that indicates you have read and understand the graduation
requirements in the catalog, which includes but is not limited to:
1. Required undergraduate prerequisite courses for your declared graduate program

2. GPA requirement
3. Grade requirements for specified courses in the graduate program
4. The letter will also act a demonstration of your writing ability. Graduate courses are writing
intensive and all students are expected to be able to write utilizing superior grammar and
proper spelling. Please note: APA (American Psychological Association) is the required
writing style at Strayer University.

II. Provide an updated resume that shows a minimum of 3 years of professional or business experience and graduate potential.

The Academic Dean will review the letter, resume, and transcripts to determine whether a personal phone interview is required. Additionally, the Academic Dean will decide if you are required to complete any additional prerequisite courses (other than those already required in the program) in order to successfully complete the graduate degree. Lastly, the Academic Dean will approve or deny admittance into University.
