Hi Hamza, JMI demands age must be less than 21 years as on July 1 of the admission year or should not be more than 20 years for LLB... For ST/SC/OBC age limit is 22 years. Basically students complete 12th by 17th or 18th of their age, In case if they crossed the age limit the nothing can be done as its their official criteria of selection...   

If you belong to other categories then you can apply as i mentioned becoz of more age limit else not possible atleast with JMI

Only one thing can be done that is apply for another good law college,,, example symbiosis college of Pune

Hope i answer your question... Gud luck
