Hyy hari, 

Yes you can take addmision in LLB course and complete your LLB

There is no age limit for the 3 year or 5 year LLB across India.

Though an age limit was introduced by the BCI, it was struck down by the court and it is not expected to come back anytime soon.

If an upper age limit is introduced in the future, it would be prospective, i.e. affect new admissions and not retrospective, i.e. will not affect students already enrolled

Considering that there is no age limit for LLB and no age limit for the Bar exam or Bar council enrollment, we can say that there is no age limit on becoming an Advocate in India.

I hope this helps
