hi,
The admission process for academic session 2018-19 is almost done at every institute, in this situation you have to wait for next academic session. As You have good score in 12th and haven't mentioned from which institute you want to do BALLB I am providing you the link of List of Law Exams.

Make yourself familiar with them and select few which are most suitable and start preparing for them or tell the name of specific institute of your interest. I hope it helps!

hello.. yes there are chances to get good college.. you can give the exam and be liable to take admission..

all the best
