It is incorrect that anyone who is in a minority group gets an advantage in admissions. There is some advantage for members of under-represented minorities (for example African American, Latino, Native American), but Asians are not considered under-represented minorities.
Your gender will, I believe, also be a neutral factor. There are many Navy/USMC billets open to women so they don't need to artificially keep down the numbers, and on the other hand they have plenty of well-qualified women applicants so they are not trying to boost numbers quickly such that women would have a significant admissions advantage.
Do your best, work hard, and I would advise considering additional service academies as well if your goal is to serve your country as an officer in the armed forces, as right now USNA is one of the more competitive SAs to get into.
Good luck!
That is what I thought, especially the gender-neutral part. I am also applying to all the other service academies and all ROTCs! USNA is my top choice, but my main goal is serve as an officer any way I can. Thank you for the advice!
