Scoring 170 + on practice lsats?

Hey, anybody out there scoring 170 on their practice LSATs? I'm beginning my studying, and I want to make sure I kill it and do it right. How are you going about it? Do you make sure that you're only studying in absolute silence or something? Always in a library/ in your favourite chair at home? Have some sort of night ritual that helps it all sink in? My GPA is 3.9, so I think I have a real chance at bringing in a high score. Much appreciated.
