Hello Student

First of all you have  to contact with the authority of NIOS of your region. Contact with them through email with a request letter to send the correct information about the date of Mathematics Exam which is showing one thing in the hall tickets and announced another thing. That two dates differentiate from each other. And this miss information creating a confusion about the date of mathematics examination of class12 of NIOS. You also request them to send you the correct date for mathematics examination of news of class 12. All the things and documents should we email on their official email ID of NIOS. The official email ID of NIOS is : rcdelhi@nios.ac.in hope this will help.
