Hey Riya.

The syllabus of BHU LLB includes the following sections- English Comprehension, General Awareness and Current Affairs, Aptitude and Mental ability and Common legal knowledge. It does not include Legal Reasoning, it only includes common Legal Knowledge. This part of the section doesn't cover Legal Reasoning. It will include the basics of different areas of Law like Criminal Law, Family Law, Torts, Contracts etc.

Best of luck
