You already have a pretty good step-up toward law school with your BA, particularly the political economy portion, so don' t beat yourself to death with anticipation. Perhaps the best prep for you would be to study independently - head to the bookstore and get Black's Law Dictionary and read it three or four times. You'll then be ready to blow away every other L1 student. Stop worrying yourself by such advance planning and unnecessary inquisitions. Have fun with your learning and don't attempt to plan-out every response to every possible scenario you may encounter.
Spontaneity is a very desirable trait for an attorney.
Anyhow, I am in search of advice. I have perhaps a million questions. I'm very interested in traveling. Well, that is probably enough for now.
