"W"s aren't unique to Kent, every university has them. I think LSAC ignores them. I have one on my transcript because they changed the time of a class I had registered for and I had a conflict, if I even remember right. Regardless, its not a big deal.
Why you would ask this here? I can't imagine. It has to do with LSAC, not Case or Kent.
Ask this on the "Applying to Law School" board if you're really concerned. Good luck.
