The National Institute of Open Schooling (NIOS) has released its updated exam schedule for the October-November 2025 public examinations. This is a very important announcement for all students in Class 10 and Class 12. NIOS had to change some exam dates because of the first phase of the Bihar Assembly Elections 2025.
