TOPIC: Army Officer Pursuing PMP Certification

Hi im a captain with 6 years of experience leading teams, managing projects, and many other stuff. Im transitioning out of the military and am pursuing my PMP so i can find work easier. I have quite a bit of experience managing projects within a military context but am admittedly not that knowledgeable with civilian project management. Currently enrolled in a program for veterans but to be honest, I tend to learn best with self-study.

Anyone have recommendations for prep books or videos, even other resources are appreciated? Apologies if this has been asked before, but wanted to give some context to my background, maybe someone with my experience can help.
