I don’t think you will ever see a completely online law school that gets ABA approval. But I know two schools, Thomas Jefferson and I think Alabama offer completely online LL.Ms now. I took two online classes in law school, both on EU law taught by EU law professors. I really liked the online classes. If your self motivated and don’t really need the professor to explain the concepts to you they are great. If my school had offered more I would have taken them, was nice to not have to be “in class” at a certain time and be able to do it whenever I had free time.
