Hello aspirant,

We know that when key is released,then aspirant presents objections if there are wrong answers ,and then the revised key is published.

Well.there is a expert core team which evaluates all the mistakes.And if you are raising challenge,kindly read all about it.

Good luck.

Hope it helps.

Dear Edwin, candidates can challenge the answer through the official website after the release of answer key. The objections raised by candidates against the wrong answer in NEET 2019 will be reviewed by expert committee and if they find objections are true then revised and final answer key will be released. The score of candidates will be calculated based on final answer key.

I hope you know about the fees for challenging a question. 

All the best. 

Feel free to ask for any query.
