Hello,

to appear judicial then you have to qualify your 12th first. There is requirement of 45% minimum for general and 40% minimum for reservation category students. There is no age limit.

You can appear CLAT which is a national level law entrance exam. you can get an admission at any college which accepts clat for admission. Not every college accepts it as they have their own entrance tests which are state level.

You can go for any level as you feel suitable and comfortable for you.

Hope it helps!
