If I was to go through law school again I would recommend photoreading. The way to photoread a law book is the same way you photoread everything else. Preview, trigger words, photoread, dipping and skimming, rapid read and mind map. Put a lot of emphasis on mind mapping, I switched my approach for the last bar exam to mind maps and it was easier to study for because of the relationships that are visible in mind maps that regular outlines don't show. You will still have to trudge through case readings but, the more exposure you will have to the material, which photoreading gives you, the better you will understand the material.
