I'm currently finishing up my first year. I am partnered and have 3 (of my 5) kids here with me, ages (now) 3, 5, and almost 15. I "plan" on school 8:30-5, plus one weekend afternoon. I usually do have to do some reading in the evening once/week. Near Legal Writing deadlines, however, working through the weekend is the norm. And I've worked through the last 4 weekends getting ready for finals.
However, I am a fast reader, so that helps a lot for my daily reading.
It's hard when I have to decide "hmm, do my homework, or go to a very interesting lunch."
A single mom I know (rising 3L) gets up at 3:30 am to do her studying then. She goes to bed when her kids do at 8:30.
