Yes ma'am I understand that. It is a very silly mistake. I have no one to blame. I usually do a thorough check after and before submitting the form, but somehow made a blunder at the most crucial time. I paid extra attention to marks and missed something as silly as DOB. I have received my Admit Card with the wrong DOB. I'm worried that IIMs who shortlist on the basis of the details in the form must consider age as significant criteria so that might cause an issue. I had quit my job to prepare for this year. Are you aware of any other students who made the same error and their further experience? That way I would get a cleared picture and then plan accordingly.
