I'm what they would probably call a gunner. I've read Planet Law School II by Atticus Falcon, and I'm following his "plan." Do what works for you, this is what I think will work for me.
Don't. Just don't. I know a handful of people who did this; they all regret it. If anything, it harms more than it hurts.
You have no way of knowing what your professor is going to cover in any given class. You have no way of knowing HOW he will cover it. Most importantly, you have no way of knowing what he wants you to learn about it.
PLS II greatly overstates the domination of BLL as it relates to the exams. Not every professor wants the same thing. Had I read an E&E for Crim, it would have lowered my grade significantly unless I was able to forget everything in the E&E.
If you want to prep for law school:
(arguably) read Getting to Maybe
(arguably) read LSC
Get a single page version of your resume polished and ready to go for the applications you will send out on December first
Get practice writing cover letters.. and perhaps research some of the firms you will apply to on December first
DON'T try to "study ahead"- not merely because it won't help, but because it has the potential to harm.
Edit: By the way, this post is brought to you by a 1L who is top 3%. I'm not trying to claim that what I say is the gospel, but it certainly has the benefit of foresight.
