Hi Rajkumar,

If the mistake is in Adhar you can change it very easily by logging onto the adhar's website and getting it fixed. you have not mentioned where the mistake is. If the mistake is in admit card then it will be upon the authority's decision but they normally choose to ignore it if it is a very small mistake. 

Good luck!

well, there will be no immense issue with the name, provide them a copy of school ID or any affidavit with the correct spelling and specify the college authorities. else, contact yes bank and hdfc bank. they make a new adhar card with proper information and correct details within urgent issues also.
