taking at least one law-related class is good to help you make sure you like discussing cases. class in logic also can be helpful on lsat.
I would say go wherever you want- but if you are trying to choose between 2 or 3 schools, pick the one that has a pre-law advisor. Ours has been an amazing resource and I don't how people at schools without one find out all the stuff that she tells us (I guess they read message boards).Also, she is very connected with the law school community so we get almost every dean/admissions director from texas law schools and some out-of-state schools as well. Very nice resource to have.PM me if you have any questions for me (doubt you will) b/c I don't usually check this board.
