Hi Ankita,

There are very rare chances for a exam to get postponed. This also depends upon the level and category of exams. If the exam is on state and national level then the chances of getting postponed is very less. The bigger the exams the lesser the chance will get. Postponing of exams also depends on various uncertain factors. It also depends upon the governing body as they can postpone exams if they find any difficulty in the processes.
