The age criteria for different boards changes. For CBSE, the age criteria is that the student must of 14 years on the appearing year. So if you are in CBSE you are allowed. Now in some state boards the minimum age is 15 and in some boards the minimum age is 14. So if you are from other board, then I would recommend you to repost the question so that we can understand which board you are in, and can provide you all the information required as soon as possible.
