A law degree is a credential educating students for legal practice. It encompasses areas like economics, politics, business, international trade, human rights, ecology, contracts, criminal law, and family law; all these form the crux of a law student's knowledge. The program doesn't just revolve around academic training but also involve group undertakings, investigative projects and courtroom exposure to give practical experience. Usual duration for obtaining this degree is three years at a law school. On finishing law school, students have to clear the bar exam to get their lawyer's license.
