Candidates have to qualify in JEE Main and JEE Advanced to secure admission in B.Tech, Integrated B.Tech and B.Arch courses in IIT-Kharagpur. And for that the candidate has to be eligible for JEE. The primary JEE eligibility criteria are listed below:

• Age Limit There is no age limit to be eligible for JEE Main 2019. However, candidates need to pass 10+2 or the equivalent examination in 2017 or 2018. Candidates appearing for 10+2 or equivalent exam in 2019 are also eligible to apply irrespective of their age.
