Hey Devesh.

BA LLB is an integrated law course that combines an undergrad degree of BA along with Law. So both subjects of BA as well as Law are included. Mostly first 3 years you study both BA and Law subjects and last 2 years you study only law subjects.

BA subjects like Economics, History, Political Science, English, Sociology etc are taught depending upon which courses a particular colleges provides. Along with it law subjects like Criminal law, Civil Law, Torts, Contracts, Jurisprudence, International law, Company law, Business law, property law etc are taught.

Best of luck
