Hey.

It is okay if you didn't apply for entrances like CLAT because you were not even supposed to apply for it if you wish to take admission in 3 year LLB.

You don't need to apply for CLAT for a 3 year LLB course. CLAT in an entrance test for admission only into a 5 year Integrated course of law which combines an Undergraduate degree with law, for example- BA LLb, BCOM LLb, BBA LLb etc. CLAT doesn't provide admission to 3 year law courses. As you have completed  graduation a 3 year LLb degree is more suitable for you. You will not have to waste 2 extra years in doing graduation again in a 5 year law degree.

Your admission will be based on your score in the entrance tests. There is no common entrance, each college has its own entrance. Few of the entrances for a 3 year law course are, you can still apply for admission.
