To take admission in one of the National Institutes of Technologies, you'll have to give an examination called Joint Entrance Examination (Main), or JEE Main.

You'll also have to PASS your class XIIth examination and the syllabus of JEE Main is Physics, Chemistry and  Mathematics of class XI and XII. Moreover, you can only give JEE Main in 3 consecutive years, like if you have given your class XII boards in 2018, then you can give JEE Main only in 2018, 2019 and 2020.

All the best!
