Hello there!

Greetings!

I am extremely sorry to tell you but you haven't mentioned the name of the application form in which you made a mistake and wants to make a correction, nevertheless, you need to wait for the opening of correction window of the applied form and once it is open then you can make correction. If you are asking about correcting your mistake in jee main application form then I am sorry but the correction window of JEE Main 2020 has closed on October 20, 2019 .

thankyou
