I go way overboard on the outlining, I know. But it worked for me. (top 10% at a mid tier 1)
First, I take notes in outline form. Then everyday I go back and clean up my notes for that day. About 1 month into the semester, I start building my Long outline. I usually cut and paste from class notes, even though they tell you not to. Then, about 1 month before tests start I start shortening my outline to about half its size by leaving out some the facts of the case and just shortening how I say things. 2-3 days before the exam, I re-type and shorten my outline and make about 5-6 pages for each class.
That's how I do it. I think working on your outlining and reviewing is more important than reading for class, even though I do that too. I know some people who read the cases 3 times before each class, but they were not in the top 10%. You'll spend your time more wisely by reviewing your past classes, not preparing for future ones.
