Start practicing for the APFT, if you are an incoming MS-I.
Your ROO will likely advise you if there are any problems with the DoDMERB. So long as you pass the APFT and DoDMERB, get good grades in your Fall semester, your AROTC scholarship should kick in for your Sophomore year.
If you work HARD and the budget allows for it, you might get your 3 year AD upgraded. My DS had his 3.0 year AD upgraded to 3.5 back in 2016.
Start running.
