I was a single mom of 5 when I started my pre-reqs. Now I am married (last Sept) but like your hubby, my hubby still works 2 states away and is home on weekends and only 3 of those at most per month. (He is SCANG AGR - for you civilians, that is Army National Guard and the AGR means he is active duty all the time, not a weekend warrior!
I work full time and am in the middle of my first term in NS. I attend the nights/weekend program. I am lucky because my youngest is 16! I don't have daycare issues and I can pretty much tell her to leave me alone when I need to study or do school work.
Because I work FT, M-Th I get up, go to work, go to school, go to bed...repeat. Friday I work but have no school. (But have to go the hospital to get my assigned patient info and stay up creating a care plan.) Saturday is clinicals.
Here would be my advice;
1.) Explain to those old enough to comprehend that you need to be free to do your school work and that they will be expected to pick up the slack.
2.) If you can afford it, hire a housekeeper 1X /wk. Let hubby do yard work.
3.) CARVE out time and schedule this as your study time. I also do studying @ lunch time during the week. My boss knows I am in NS.
4.) Go to campus early or stay late for an extra hour of study time here and there.
5.) If you have family in the area, see if you can get someone to volunteer to help every so often.
It can be tough, but it can be done. I just tell everyone that I am keeping my eye on the goal. I have foregone all social engagements until I am finished and things will get tough later....hubby leaves for Afghanistan in Jan so I will be w/o him for a year.
