See the minimum qualification criteria for BA is that you must have a graduation degree with 50% marks (5% relaxation for candidate of reserved category) from any recognized university/college.

Now for most of the college CLAT is required. The best colleges in India offers admission on the basis of entrance examination. So if you want to get admission in top institutions for law then I would say you should prepare for the entrances. Although some universities takes there own entrance which you have to qualify.

Thus for most colleges you either have to appear for State/National level entrances or you have to appear for insitutional entrances. Now if some university offers such admission then you will be eligible based on the criteria of eligibility introduced by that department.

Some of the most preferred entrances are provided below:

Common Law Admission Test (CLAT)

AISECT Joint Entrance Exam (AJEE)
