Dear aspirant..........

The examination authority, National Testing Agency will provide an opportunity to candidates to challenge the doubtful questions in NEET 2019. Candidates can challenge the answer through the official website after the release of answer key. The NEET 2019 official answer key is likely to be released by May 30 and challenge can be made within the prescribed dates. 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.

How NTA will resolve wrong question in NEET 2019

The examination authority may resolve the discrepancy of wrong question in NEET 2019 in following ways

Case 1:

In case 1, if NTA official answer key reflects these same questions with incorrect answer options, then NEET 2019 examinees stand a chance to get 12 bonus marks for the two questions with wrong answer options.

Case 2:

In case 2, NTA may calculate the total marks for NEET 2019 barring/excluding question number 8, 13 and 81 of Set P2. In this case, the total number of marks will be calculated out of a total of 708 instead of total 720 marks. 

Hope this helps you out.......
All the best:)

If someone challenges a question in NEET and gets his own answer to be correct then the new answer will be considered for all the candidates. But then the authorities won't tell you if the answer to the question that you have challenged is right or wrong or what is the new answer.
