OP, this is really the crux of why your idea isn't feasible.
In addition to having a professor and (probably) TAs who can answer questions for you, your 1L classmates are there to serve as resources. When we were covering difficult topics like the ones Nony brought up, our first course of action was to ask the TAs for clarification, and our second course was to talk to other students in the section, because even if you didn't quite understand what the professor was saying, odds are that one of your classmates did. Under your plan, you'd be "ghosting" the classes, and even if you didn't get your ass kicked out after a week, you wouldn't be able to rely on your classmates for help figuring out the harder points of law.
Also, maybe it's just schools in urban environments, but don't these places check your ID before you go in the building? When I was shadowing some classes in Chicago, I had to get a pass from the admissions office.
