The study of Law is a ruling system, a set of rules and regulations which applies to all members of a society governed by the judiciary system of that country.
A course in Law teaches you the right skills to practice law. Students taking up law must be good in debating and see things at every angle. They need to be analytical and critical, not agreeing to disagree and not take the easy way out to solve a problem. Students get to choose which areas of law to specialise in; corporate, criminal, civil rights, intellectual property, etc. Lawyers are well-trained advisors to their clients, providing support in a variety of legal matters, civil or criminal.
