Dear Ayesha, minor errors like alphabetical mistakes in the address can be ignored. For example, my house address is Priyaas *****"". But if I enter Priyas, it's still ok because the address is only for authentication purposes and that doesn't affect your ranking or merit for NEET. Mistakes like Category, Gender, Date of Birth, etc are errors that need your attention because they affect your merit. And NTA doesn't communicate through your mailing address. Every commCommunica is online through your registered email id and contact number. Just ensure that they are correct. Rest, relax and just concentrate on preparing for the exams. Good luck!
