Usually either your study centre or the locations closer to your study centre are allotted as Exam centres for NIOS exam for both 10th and 12th exams. The exam centres are allotted based on your preferences during filling the form for admission and so it is mostly unlikely that any change in the exam centres will be entertained. Having said that, Candidates can still request the Director of Evaluation for change in exam centre by paying Rs. 1500. The exam centre can be changed upon the approval from the Director of Evaluation. For more information, please visit our page at: https://school.careers360.com/articles/nios-exam-centres
