As there is no option to modify the currently filed application , You may wait till the time of Document verification. At the time of document verification, you may tell that by oversight the same happened , produce all the relevant documents proving the right details, you will be admitted. No other issues, But while applying for other exams, pls take extra care to fill the necessary details. Start preparing for exams, stay focused, you will be able to clear the exams. If any doubts, pls feel free to ask.

Wishing You Good Luck !
