I keep asking my professors about how they grade the exams and how to do well, but I get nothing out of them but vapid platitudes about "arguing both sides" and "writing clearly and concisely."
Law school is so unfair that way. Everything is so arbitrary and unclear. I'm reading a book by Duncan Kennedy that totally rips on the entire law school system, and I love it. He mentions how law school cultivates a few legal analysis skills in the minority, whereas it could have constant feedback and really turn everyone into a great lawyer.
