re: Which is harder? Engineering, Med School, or Law School

I would say law school is definitely the least difficult but that is from my own point of view. The thinking needed for law school just comes more naturally for me. Rather than say med school, having to memorize copious amounts of information and then regurgitate it.
Also I've been interested in Law my entire life and never had any notion of going into the other fields. Its based largely on the way you think and how hard you are willing to work.
