Yeah I'm pretty curious about that too, I've heard mixed reviews about whether it's good to prepare before 1L or not, ranging from go take a pre law course to nah, just relax over the summer. Hoping someone could give their input!
I wonder if this is another move to encourage more people to go to law school on a broad scale (just the like the recent Harvard-accepting-the-GRE-in-lieu-of-LSAT) development?
