Hii Diksha!

It is usually warned by the teachers to fill the details correctly in the OMR sheet. But, now that you have commited it, nothing can be done. But, since you have the bubble on the right one too, your mistake may be ignored and there should not be any problem though. But, if it happens, you may opt for correction of details and then get it corrected by the official authorities.

Hope this helps.

Good luck!
