Hello,

A candidate can appear for JEE Main for three consecutive years from the year of passing in the qualifying examination. A candidate appear for JEE Advanced for two consecutive years from the year of passing in the qualifying examination. You can appear for Class 12th examination second time and apply for JEE Main as there is no age limit to appear for JEE Main. But there is an age limit to appear for JEE Advanced. The upper age limit to appear for JEE Advanced for general category candidates is 25 years in the year of admission. A relaxation of 5 years on upper age limit is applicable for candidates belonging to SC/ST category. So if you fulfill the age criteria you may appear for JEE Advanced after appearing for class 12th examination second time.
