The OMRs are also evaluated on the same day with the help of the answer key provided by CBSE. Although every possible care is taken, there is a possibility that in the question paper, there is some mistake or some answer is wrong in the Answer Key.
CBSE has a well settled system to address such issues. It has already been communicated that if there is any observation about the question paper or answer key,the same should be sent to CBSE after examination is over. Under no circumstances, this should be made public prior to the time when examination is over as this exposes the question paper.
In case of any mistake in the question paper or some answer is wrong, students may reply the question as per their wish. The evaluators may check/evaluate the OMRs according to the answer key provided to them.
As mentioned above, CBSE has a well settled mechanism to act on the observations received about mistakes in question paper or in answer key based on the recommendation of the subject experts at the time of preparation of result.
It is requested that this information be disseminated amongst the students appearing in Term- examinations.
