I am a little worried about that statement, @geolawyer1903. Please don’t neglect this important aspect of your life, even if it is just to develop the “soft skills” you will need as an attorney someday.
I disagree with some on here about how many hours you can work. It is somewhat dependent on your major, and of course the university (you will find ironically that some of the highest ranked schools will be the “easiest”), but 20 hours should be easily doable with some modicum of efficiency and focus on your part. I wouldn’t counsel more than about that number.
