My nephew was accepted at West Point last year. He wanted to go into MI and was well along in his Mandarin Chinese studies from his travels, summer school and HS. He was also accepted at Georgetown. Because I had worked in college admissions and been in MI, my brother asked for an opinion.
There are a large number of very high quality schools that offer Army ROTC. See http://www.goarmy.com/rotc/courses-and-colleges.html. The list is organized by state. The schools that have the ROTC program directly on their own campus are followed by an indented listing of participating area schools. Four year scholarships are very common in areas of study where the Army has a high demand, some e.g.'s are Chinese, Arabic and most any engineering field.
Academically speaking, you are qualified. Pick some candidate schools and call the ROTC commander directly. If they want you and have full rides available it helps admission. Cast a wide initial net as there are some very strong programs out there that you may not know about.
Transfer admissions are often more difficult than freshman admissions in majors of high demand as the university must first meet the faculty work load needed for current students. Good officers realize the need to take on challenges.
My nephew selected Georgetown. When I was a student at WPI we had transfers from two of the military academies in my fraternity house. While working there years later in admissions, the son of a friend was funded through his PhD in biology by the Army. Army Lt General’s Harry Storke and George Hazzard were two very important pioneers in the development of a revolutionary change in the design of an engineering education at WPI.
Picking the learning environment that fits you is more important than most HS seniors are aware. The importance of this fit impacts the total learning experience and is not always measured in GPA. If you have not done it already, you may want some confidential discussion with a knowledgeable advisor at WP.
