It depends on your state. In california(or if you plan to move to california after graduation) you can take online courses if state approved. Concord and Taft are both accredited and approved, but not much good out of that state.
Apprentiships in CA work if you can find a lawyer in good standing with 5 or more years in that state to work under for a few years and then take the bar yourself. Other states require at least a years law school before applying for it. CA is the exception but unless you already know a lawyer there willing to sponsor you I'd say dont get your hopes too high on finding one.
If you want to go part time Cooley in Michigan has 5 year plans and weekend only scheduling too. They also only require an associates degree to start(same for Taft online) http://www.cooley.edu
you can apply online for free and they are ABA approved.
This forum has a "distanec learning law school" section if you want to read some of the posts there too. Just dont fall for Novus, they claim to be a school but arent accredited and cant let you sit the bar anywhere. They'll try to lie to you, dont fall for it.
