Hello aspirant,

Hope you are doing absolutely great.

So with regard to your query, YES a Tamil Nadu state student can get seat in NITs and for this one need to complete 12th standard with PCM and give the JEE Mains exam and get a higher percentile between 90 to 99 and then you will really have better chances to get NITs, even IITs, if you had written the JEE Advanced exam.

The National Testing Agency is the competent authority which conducts the JEE Mains exam every year. For any information regarding JEE Mains exam, checkout this link: https://engineering.careers360.com/exams/jee-main
