As far as I understand, each academy admits about 1200-1300 or so cadets/midshipmen each year. By a classes senior year, the class size is roughly 1000 cadets/midshipmen. I have heard that among other reasons, some of the kids voluntarily drop out, some go to another school, and some are dismissed for medical reasons. What are the medical circumstances that would cause a cadet/midshipmen to be dismissed from an academy? Also, is it common to be dismissed as a result of your commissioning medical exam or do they usually work with you to make sure you graduate, even if something negative turns up during the commissioning exam? Thanks.
