Icse — I sent wrong date of birth

Address:

Gautam Buddh Nagar, Uttar Pradesh, 281121

I had my registeration in 2012 in an icse medium school and during that registeration process my date of birth went wrong. I did not pay attention to it but lately i have been facing a lot of trouble as many of my official documents are stuck because of that wrong birth date. So is there any way through which i can get it changed because it is creating a lot of trouble and my other documents could not be verified because. Of this issue.
Also many very very important documents and files are on hold only because of this mistake.
Please please look into the matter as it is very urgent and provide me the solution as soon as possible. I will be very greatful it you help me out with the same. Thank you
