Dear Shankar, NTA has clarified that students can appear in JEE Main twice a year in three consecutive years from the year of passing their class 12 exam. This makes JEE Main number of attempts to six in a span of three years. Also, for the age limit, there is no age limit set by NTA to give jee mains but only in span of three years from passing 12th.

All the best

Hope this helps

Hello,

A student can apply and appear for JEE mains for 6 times if he appears for both the sessions in a year. He can appear for 3 consecutive years from the year of passing the class 12 examinations and can appear for both attempts in a year. Hope this helped!
