Hello,

There is no way to change it now. You can write a mail to the board stating the mistake and ask for solution but they might not consider it as they gave you chance for correction.

This is why it is said to check the form before submitting. Due to this reason board also gave time for coorrection still if any mistake is there then that can't be helped. It will stay and the same will go untill the counselling process. There might be some issue while document verification. It depends on the officials if they will consider it or not.

Not to worry go on with the process and give jee again in april month with accurate details and go with that.

Hope it helps!
