WMCL rising 2L here...The Mitchell Library has a bunch of resources and lists, including the following list of sources with briefing advice...http://www.wmitchell.edu/library/documents/briefcase.pdfWhile I think it is a good idea to get familliar with briefing before classes start and develop a system ahead of time, be aware that you will most likely need to adjust and adapt once you are in the day-to-day. Over time, parsing the signal vs noise becomes more second nature. A few profs are gotcha types who might quiz you on the semi-obscura to check for slacking and/or to keep the class on its toes, but I believe the vast majority of the faculty at wmcl tend to be concerned with the core parts of a case that made it worthy of inclusion in a casebook to begin with. If you happen to have one of the gotcha types, you'll learn that soon enough, and can adjust accordingly. As you go, revisit your previous briefs, and ask yourself if they...(A)were helpfull at the time (in-class discussion of that case/theory) and(B) likely to be helpfull at the end of the semester (or whenever tested)function trumps form
Be aware that many of your classmates are not briefing at all or are only taking notes in the book. I think that your briefing version may actually put you at a disadvantage. First, it's not brief (boiling a case down to esential facts). Second, it includes elements that will not be on the exams. Remember that looking good in class (often worth 0%) and looking good on paper for exams (often worth 100%) are different.I'm not preparing for class. I'm preparing for the exam.
