Wow - a lot of questions there!What do you mean by "prelaw type questions?"
So, require some sort of MCAT-like test but for law school? Not sure what you'd have to learn...history, political science, philosophy? English? All of those would arguably be on the LCAT.™ (Just made that up)
How would one learn those fields as an undergraduate? And would learning facts about the common law or general principles of criminal law or whatever really evaluate how apt one is at being a lawyer more than logical reasoning? Hmm
