Hello Ravi,

The minimum age limit for JEE Main is 17 years.

As per the JEE Main Eligibility 2019, the candidates must have born after 1st October 1994 i.e. they must not age more than 24 Years while appearing in the exam.

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.

The eligibility criteria for JEE Mains 2018 says that the candidates belonging to any of these categories – ST, SC, PWD can be benefitted with 5 Years of Age Relaxation.

So, if you fulfill the given criteria then yes, you can sit for JEE Main 2019. But, based on what you said I don't think you are eligible for JEE Main 2019.

Hope this helps.
