After CBSE had conducted NEET UG on May 6, 2018, coaching centres had released answer keys. It was debated that 12 questions were wrong in NEET 2018. According to students and teachers, 4 questions seemed ambiguous in Chemistry, 2 in Biology, and 6 in Physics. However that was according to the unofficial answer keys, and everyone was waiting for the NEET 2018 Official Answer Key which finally released on May 25, 2018.
Surprisingly, there are no wrong questions in the paper as per official answer key of NEET 2018. However, students were openly invited to submit challenges or report discrepancies in the paper. Deadline to submit challenges was May 27, 2018.
Now CBSE will look into all the challenges and consider them. Subject experts will review the answers and decide on finalizing answers. This decision will be final.
Bonus Marks For Wrong Questions In NEET 2018
If the board finds that there were any wrong questions in the exam, or questions which had ambiguous answers, then it gives bonus marks. Bonus marks in NEET 2018 will be given to all students if such questions are there.
Who will get bonus marks in NEET 2018 if there are any wrong questions? Only those who have challenged? Or all?
This is the most frequently asked question about this topic. Please note that CBSE will award bonus marks to all candidates if there are any wrong questions. Even those who haven’t answered the question gets bonus marks. Actually there are no written rules about this in the brochure. However this is usually what happens in NEET and other major entrance exams.
As per NEET 2018 Official Answer Key, there are no bonus marks in NEET 2018; yet.
In the answer key released on May 25, 2018, all questions have an answer. As per that key, there are no bonus marks. Last year, the answer key had two such questions in which answer was marked as “5” indicating that they had no correct options. Students got bonus marks for those.
So are there any chances of getting bonus marks in any question in NEET 2018 now?
Yes, there are still chances. CBSE is yet to review the challenges. If after reviewing, it decides that some questions are fit to deemed as wrong, then bonus marks will be awarded for those. There is no clarity yet whether 4 marks or 5 marks will be awarded for it. In either case, it will be same for all.

Well, NEET 2018 Official Answer Key was quite disappointing for all those students who had found the above questions to be ambiguous. Not only were many unable to answer them, but also they had to waste a lot of time on them.
Now that challenges have been submitted, and we are sure many candidates must have challenged these questions, some result may come out of it.
Few of these questions don’t seem controversial now that official answer keys are here. However a few, at least 2-3 seem to be dicey. Students are waiting for final decision of CBSE in this regard.
Do you think CBSE should award bonus marks for any question(s) in NEET 2018? Share your thoughts in comments below. Also, best of luck for NEET 2018 Result!
