I am in class12 when I was apply for admit card and other things for law exam
Dear Ayush,
Now you are in class 12th you should apply for Law entrances exam like CLAT, AILET, MHCET and other universities entrances examinations when their applications are out. Generally their applications are out from the end of December. Apply as much as entrance examination you can give and prepare for that with full determination.
Best of Luck for your future.
