Dear candidate most often when you enter wrong information you get a notification from your examination authority that some discrepancy has been found in your document and you need to remove it within the stipulated time. There is high chance that they would give you the second chance to rectify your mistake but if they find it to be a major one then you may not get a second chance. Stay positive, hope you get a second chance as I discussed, don't make any further mistakes.

Good luck!!
