Interesting week, but I have a couple of comments. First, in my 2+ years of law school, I've never seen or heard of anyone getting kicked out of a class for not reading. My friends at other schools have never seen this either. Unless it is a student who is consistently unprepared, I think it is poor form on the professor's part. It is fact that there are times when you are just not as ready as you could be for a class. That does not warrant dismissal from the glass. The consequence at most normal schools is that the professor grills you the next class. If I were ever kicked out of a class for simply not being ready once, I would take issue with the professor and elevate the matter if need be. Then again, law school administrators generally are poor at their jobs, so it likely would not go anywhere.
As for your weekend studying, be careful. While each person needs to do their own thing, studying all weekend will inevitably lead to burnout. It's a marathon, not a race. If you do not allow yourself to relax, rest, and have some fun, you'll be in bad shape come finals time.
