I'm a part-timer, just finished 1L. I go to a lower ranked (between 50-100) at night, after work. I was forutnate enough to drop my hours from 40 to 32, just so I could have some sleep and sanity time.
Going part time does not save you tons of time, you only take one less class per semester (Con law and Criminal law for me). My 1st semester was Intro to Law for 2 wks, then the remainder of the semsester Contracts, Torts & Legal Writing (11 credits). 2nd semester Contracts II, Property, Civ Pro & Legal Writing II (12 credits). It is not easy and you will have little time left for family and friends. I had class until 10:30 at night 2 nights 1st semester and 3 nights a week 2nd semester (and sometimes four to make up snow days!!!!!!!!!) You also miss out on things like clinics, unless you can find a way to get time off during the week. The advantage is I was able to work and still be able to pay my mortgage while attending school. If I could afford to go full time without working, I definitely would.
On the plus side going PT forces you to be organized (as you already know from going PT in the past) and you will probably do very well. My class has many students who do not work in the evening program (though many are planning to transfer to FT this semester). I've heard that many schools will admit students who could not make it into the FT program into the PT one because PT didn't count towards the US News Rankings, but I don't think this is true anymore (I'm sure others on this board will know).
Good luck whatever you decide to do!
