Hello aspirant,

The Joint Entrance Exam is an entrance exam which is conducted for providing admissions to various engineering colleges like National Institutes of Technology ( NIT's),  sundown Institutes of Information Technology ( IITS)  and colleges such as centrally funded institutes.

There is no minimum age criteria to appear in Jee Main examination. Only the criteria to appear in Jee Main Examination is that the student should have passed 10+2.

Hope that helps you

Thank you
