Hello Riya,

BHU LLB is a three year law programme which you can apply after Graduation and BHU BA LLB is known as BLAT, It is Five years Integrated Law programme which you can apply after 10+2. Both are the different programmes. If you are preparing for BA LLB programme then you can prefer CLAT or any other five years law programme study material as the syllabus is almost same for the Five years Integrated Law programme.

Good Luck!
