Can my command tell me my college school work isn't important?

Have you heard of the phrase, "Needs of the military take priority...."? You have enlisted in the US Army. You are charged with learning everything you can about your MOS to be the most effective Soldier you can be in performance of your primary duties. College work, while encouraged, will always be secondary to your military obligation. I dropped from several classes because my duties prevented me from attending class. Incidentally, that didn't change much after retirement either. For some reason, my employer expects me to be on the job instead of a classroom.

Yes it is mission first, like everyone else has said.

Personally I would just take one class at a time and complete your school work after work. It is all about time management. It might be hard for you to complete but you will also thank yourself in the end. With that being said do not enroll in a course if you know cannot complete the work. Otherwise you might have to pay back money if utilizing tuition assistance.

Also, I am not sure if this program still exists but it may be worth researching.
