Hello Aspirant

The mismatch between your school address in the JEE Main registration form and that in your Class 12 board results will not create a big problem during JEE Advanced registration or counseling.

The school address in the JEE Main and JEE Advanced is mainly used for contact purposes. Provided that the contact details, viz., your email address and phone number, declared in the JEE Main application form are correct and updated, you would be able to receive all the communication and news about JEE Advanced.

Hope this helps

One can also at any time contact the JEE Advanced authorities in case of any discrepancies so that one's application is correctly under process.
