Law

Currently for students, who aspire to become lawyer after 10+2, 5 years integrated BA LLB or BBA LLB course offered by multiple universities is the best option. National Law Universities are best option for 5 years integrated law course. NLUs conduct All India Law Entrance Test for 5 years integrated 5 years law degree courses for admission to law universities in India. Lots of private universities also offers five years integrated law degree such as BA-LLB or BBA-LLB or B.Sc-LLB.
In case you are unable to get admission in 5 years integrated law course then you may opt for 3 years law degree after graduation degree. Various legacy universities and its affiliated colleges offer 3 years LLB degree course. The degree entitles the graduates to practice law. Most of these universities conduct their own entrance examination. Graduates of all discipline are eligible to seek admission in 3 years law degree course.

Both the courses are entirely different and need different eligibility criteria. If you already are a graduate then go for only LLB or integrated LLB-LLM. In case you just did your 12th, then definitely you should go for BA-LLB.
Doing an integrated BA-LLB is going to save your fee, life's one precious year as well as the test of clearing a test after graduation where the level of the test becomes difficult.
There are many good universities like National Law School, Lovely Professional University, Panjab University, Chandigarh University, etc., that are offering integrated BA-LLB. These institutes have varying eligibility criteria. Some offer admission just on the basis of CLAT/LSAT, some offer admission on CLAT/ LSAT/ their own test, some offer admission just on the basis of marks in previous qualifying exam and some offer admission on the basis of CLAT/ LSAT/ their own test/ marks in previous qualifying exams.

Good luck.
