The National Testing agency (NTA) released the answer key of the National Eligibility and Entrance Test (NEET) on Wednesday, but the candidates seeking admission to the undergraduate courses are unhappy. The students who appeared for NEET can send their applications to NTA challenging any question or answer asked in the examination with the help of the answer key. However, in the absence of their Optical mark recognition (OMR) sheets or answer sheets, the students say they cannot send applications.

An application to the NTA costs R1,000 so the students cannot send in their challenges without a certainty, said students and parents. The deadline to send applications ends on Friday.
