Sharp comprehension skills are needed as legal outcomes can depend on the choice of one word. Writing will be as important as reading. Few will be prepared for legal writing with its conciseness, precision and need for that certain style to set you apart from others. Even if you have never spoken before a crowd of more than two, you may find yourself reciting before 100 fellow students. While not absolutely necessary to complete legal training, it will help to be articulate, to be able to think on your feet and respond under pressure.
Most schools use the case study approach.
However, memorizing cases is not what it's all about. The study of law is not an exact science. While some areas of the law are rooted in ancient history, other areas change almost daily. You will find that while you cannot carry all the answers in your head, you can carry the ability to find these answers. It will be difficult to specialize in any particular course of study.
