Candidates who will be appearing in the qualifying examination (10+2 or equivalent) in 2019 will be able to appear in JEE Main 2019 both January and April Session and thereafter in JEE Main 2020 and JEE Main 2021.

Since, best score out of two attempts every year will be considered by the admission authority, therefore, candidates will be able to appear for a maximum of 3 attempts in JEE Main. Also, age will also be the deciding factor while applying for JEE Main entrance examination.
