Lsat prep; law school admission

<p>Currently, I'm a community college transfer student, and I plan on transferring to UC Irvine. I have about two years left of school until I received my bachelor's degree; I'm working for a double major in Criminology & Psychology. My question is: should I start working on the LSAT right now? What kind of books work best? Also, I have three "W's" on my transcript, will that be a problem? My GPA is a 3.56. My goal is to be accepted to a number of top schools. For example, Stanford, Berkeley, Davis, UCLA, USC, and UCI; I want to stay local. So, any advice?</p>
