Your friend is right Louisiana is the only state that has Civil and not common law and this would be somewhat of a challenge. Although I imagine the first year curriculum at Tulane is the same as any other ABA school. When making your decision about a law school outside of the T14 i.e. Harvard, Yale, Stanford, etc location & cost should be your number #1 concerns. If you have no desire to end up in Louisiana don't go to law school there. If you want to be in Louisiana then Tulane will probably work out fine.
