Law

You are eligible to seek admission in 3 years LLB degree course even after BE IT as graduates of all disciplines are eligible to seek admission in 3 years LLB degree course offered by majority of Universities. You are advised to appear in LLB Entrance Examination conducted by legacy Universities.

As per current policy you are eligible to seek admission in 3 years LLB after BCom as there is no age limit for LLB examination this academic year of 2017-20 batch, as the Supreme Court has stayed Bar Council of Indias (BCI) notification fixing age limit for law courses. Age Policy on 2018-21 is yet to be declared.

Some of the top colleges to pursue a certificate course in Human rights are as follows:
1) ILS law college, Pune
2) Bharati Vidyapeeth, Pune

While there are a lot of publications, one book, I know for certain, quite a few students refer to is the Guide Book by Eastern Book Company, Lucknow.

In terms of age, NLU has withdrawn the age eligibility criteria for AILET 2017. You may have to wait for AILET 2018 admission notice to check eligibility. As per my understanding, you will be eligible to appear for AILET.
