I think you are right on the lack of feedback/being efficent comments. It's probably what causes the most problem.
What practical solution do you have for these problems? Since you claim you are doing well, would you mind sharing your techniques to overcome these difficulties? I would really appreciate any help.
Unfortunately, I don't really know. Only thing I've done that has helped me is to find good supplements, and make sure I have an outline that is focused on exams; which means they aren't 100 pages long. Just narrow stuff down as much as you can, you should be able to get a class down to around 10 pages I think. Keep in mind that a lot of your class mates will be gaming professors; especially 1L (if you have electives) and first semester 2L. They'll be taking easy A classes instead of stuff that's actually relevant to them. If you want a job with high focus on GPA (i.e. all of them), you'll want to do the same thing. ratemyprofessor.com is your friend.
Also, don't spend time trying to impress your professor in class. That means 1) don't be a gunner. Nobody likes a gunner. Usually that includes professors. 2) Don't spend too much time worrying about the game. Nobody really gives a crap about every little detail in Palsgraf; if you find and remember the black letter law you're good. That's all you really need to know.
Since me and Thane are starting to agree on things (and I still haven't read his book), I won't bother replying much since I think we're on the same page. I'm also not saying you should be a slacker in law school; indeed not. Just don't let it be everything that matters in your life. For 2L and 3L years I've had a policy of never taking books home. Once the day is over, it's over. That has been good to me, it means that after 6PM most days, I don't have to think about law school at all. It's great.
That's not solid advice for a 1L though, 1L year just has to be horrible, sorry. You don't really have the study technique or experience to be efficient in your reading, you also have a heavier course load than in 2L and 3L years (for some reason that is absolutely beyond me).
