Hi aspirant,

You got your result of jee main paper 2 on yesterday & it was filled wrongly. I am very sorry to say that ,probably, you can't get a chance to change that. According to the authorities, no correction can be done by them after declaration of result.

But still, you may contact them saying your problem.

Here is a college predictor tool. It will  help you if you are able to change that successfully.

All the best !!

:)
