I am planning on studying something science/medicine related. Probably biochemistry, chemistry, neuroscience, genetics, or oceanography.
All of the service academies, save for possibly the Merchant Marine Academy, have a guaranteed job waiting for you after graduation.
Also you can look at colleges that otherwise interest you and look at their graduate surveys…it shows the % of graduates getting jobs.
But your future success will rest on your shoulders, how you do academically, the relevant experiences you gain while in college, and to some extent, recommendations.
