My DS was a re-applicant who just received an appointment. What did he do?
1) Because admissions told him his biggest weakness was his ACT scores, he signed up and took an ACT improvement course. Math score went from 27 to 32.
2) Enrolled at the local community college and took Calculus I, Chemistry I w/ lab, English Composition, and US History. Got a 3.8 GPA during the Fall semester. One thing to watch out for is colleges and math placement exams. If you don't have high enough AP scores or have high ACT math scores, most colleges will require you to pass a math placement test to take Calculus. DO NOT take this exam lightly, because if you don't do well enough, the college will force you to take College Algebra or College Trig. The academy's will not be impressed with any math below Calculus.
3) Trained hard for the fitness test and ensured he had a higher score than last time.
4) Completed his application - this may sound obvious, but over half the re-applicants do not complete the application.
I know community colleges may not have the best reputation, but they have a few advantages for re-applicants. First, you will actually know your instructors personally making it easier to get the required evaluations and second you can live at home. Also MMI and NMMI are just military community colleges, so academically there is no advantage.
This is A WAY that worked, but it is not the only way. Do a self evaluation and determine what is best for you.
