<p>Both the Naval Academy and Coast Guard Academy have one week summer programs for students after their junior year to give then an idea what the academy is like. One mother told me that this starts the application process at the Naval Academy (but you still need to submit tests, transcripts and the recommendation). The Coast Guard Academy does not require a congressional recommendation.</p>
<p>As for becoming a doctor, there is an Army program I believe that takes college grads and sends them to medical school. The student is then obligated to serve one year for each year of scholarship (? - if you spend four years in medical school, you serve four years). I knew several people who did this.</p>
