Hi aspirant,

In the mentioned scenario, you should enter the date of birth as on your marksheets. See it could create a hinderence in future during the counselling process or at the time of documents verification. The best possible solution to it could be using any other government authorised birth proof such as AADHAR, Pan card or driving licence which has same dob as on your certificates. Else you can apply for correction in your birth certificate which is comparatively much easier than getting marksheets updated.

Hope it helps!!
