My daughter started her freshman year on a national 3 year AD scholarship, which meant she would need to pass her physical fitness test prior to contracting sophomore year, however, at her school the school covered room and board all four years even for 3 year winners, but she had to pass the test to get that benefit and she trained during the summer and had no problem passing. However, there was another nursing slot not filled by scholarship recipients and 3 or 4 other nurses showed up as freshman to compete for that spot (it was a nursing mission spot for 2020, and at the time that was an allocated campus base scholarship, things change though so do not know if it still works that way) One of those that showed up, another female, did not do well on her first APFT (this was in fall 2016) She only completed 3 push-ups and did not finish the run because she threw up half way through. I am not saying this to shame her, but to tell you she was the one who won the 3 year campus based scholarship and is currently a 2LT nurse in the US Army. She worked really hard her freshman year and she excelled at fitness the rest of her time there. And you have time to train and pass in the Fall.
DoDMERB is a whole other issue, the fracture that did not heal right might be a barrier to contracting, or you might be able to overcome it, it isn't a big enough of a reason to stop your goals and not try though!
