Dear student,

National Testing Agency will provide JEE Mains application correction facility from January 19 to 21 for February session exam. If you have made any error during the filling of JEE Mains application form, then you can correct it during the correction period. To make corrections in your form, firstly you have to visit the JEE Mains NTA website. There you have to login . And after that you can make corrections if needed. And there is not any problem, on correcting the application form. But let me tell you that, you can't edit all the things in application form. For more info, visit the link given below.
