I am new to this forum. First things first: I am a Junior undergrad at University of California, Riverside majoring in Anthropology. I have my mind set on law school post B.A. and I already have a few schools in mind. However, I must conquer this monster known as the LSAT

I want to begin studying now rather than cramming later so I was wondering if anyone has used the LSAC prep materials? If so, more specifically, has anyone used the LSAC SuperPrep book??
Also, I intend to enroll in the Princeton Review course at the beginning of my senior year so would the LSAC prep stuff cancel out or enhance my Princeton Review LSAT prep?
Thank you in advance to all those who reply!
