I care if Harvard is hard or not, because I appreciate academic rigor (one of my major motivations to get into the law) ...oh, and I was inches from academia until a settled on the law
I don't know if I would classify law school as academically rigorous. I mean there are pretty much two extremes rampant grade inflation at the top schools and rampant grade deflation at the lower ranked schools. After the first year it's really just cruise control at that point, but the first year the hard part is figuring out HOW to study not so much WHAT you study. I know several people who were hoping law school was more academic than it turned out to really be (when compared to something actually academic like a Phd program) and where disappointed. Although beyond the JD, the LLM and JSD can be more academic than the first terminal law degree.
