Any Current or Prior Law Students? Have any advice?

I am currently going into my senior year at UCLA. I am an anthropology major and central and eastern European studies minor. I currently have a 3.87 GPA. I have not taken the LSAT yet, but did a practice test (while traveling on an airplane, but maintained proper timing) having absolutely no prior knowledge about anything LSAT related and my approximate score was a 148. I am currently in an LSAT prep course and am registered for the December 1 exam. I am a little freaked out by this low practice test score, but my instructor has urged me to avoid worrying because I went into the practice test without seeing/reading/studying anything relating to the LSAT. Current/Prior law students: Is it realistic to be applying to schools like : UCLA, Stanford, Berkeley, USC? Have you applied to these schools? Did you attend? If yes, Do/Did you like it there? If you have attended and graduated, were you able to find employment? If it helps to provide more background information, I am a (soon to be) 24 year old resident of California and I am female. Thanks :)
