I finished top 10% and I've never been in the top third of anything, simply by doing the work: reading, briefing etc. It may take more time but believe me, for the few people that do it, it pays. Canned briefs will only tempt you to get lazy.
I dissagree to a point. I finished in the top 10% and I used legalines only as a support. I would quickly read the canned brief and then read the case. ALWAYS READ THE CASES! After reading both, I would compelte by brief (usually book brief).Another thing to remember is to find out if your prof likes to have you recite the cases in your exams. Example - World Wide Vokswagon, Gore v. BMW... In those situations, you better know those cases.
