How hard would it be to complete a degree while being a Ranger Medic or Flight Paramedic?

I was a Ranger Infantryman, and I would say it would be nearly impossible to complete an online degree, and completely impossible to complete a partially in-person degree (unless, maybe, you can fit your in-person classes into block leave).

I cannot speak to the Ranger Medic piece, but as a flight paramedic it is absolutely feasible to complete a degree in active duty. Many hours on 2nd up shifts or on 1st up waiting for the bell to ring and you to rush our to your aircraft allow for plenty of time to do schoolwork if you manage your time appropriately. In addition, with the credits you’ll receive for training as a paramedic, it gives you a nice jump start to completing an associates degree. Hope this helps!

Damn tough, impossible to schedule around emergency exercises, deployments, field exercises, etc.
