Joining AFROTC

Hi everyone! I am planning on joining AFROTC next fall and was wondering if anyone had any advice for me. I’m pretty physically fit since I run track and do powerlifting, so I am not too concerned about that aspect. However, I really don’t know much about the military in general as no one close to me has ever been a part of it in any way. So, I would love to hear if there’s anything I should definitely know before starting or anything I can do/study over the summer to help me prepare.

Thanks :)
