Hey Candidate,

The answer key for each exam is released by several coaching institutions and other publications, but the Answer Key released by the Official Conducting Agency is only taken for calculation.

If any candidate has any doubt regarding the correctness of the Answer Key and he is confirm that the answer released is incorrect, then he/she can apply for the Answer Key Challenge and submit a certain fee for rechecking the Answer Key. If the claim is found correct, then the money is refunded back and the paper gets checked on the basis of the New Answer Key. But if the claim is incorrect, no refund is done.

Hope that you have got your answer!!
