Med services is very competitive at WP. By law it is limited, So Cadets who enter a major of health sciences are identified way early on in there academics. (towards the end of there Plebe year) By the time they get to Cow year, there are about 40 to 45 who have survived and then they list cuts in half then half again. The department head who hold the keys to select those who go on to Hopkins Med school is a civilian and very picky. (politics) So those who are selected are usually in the top 5% or less in the class.
In my opinion, seeking med school through the Army is not very efficient. You may be better off with ROTC.
Please take a look at how branching works. It can be done!!
