NEET provisional answer keys are those which are released by the National Testing Agency (NTA), approximately a month after the conduct of the exam. As the term suggests, the provisional answer keys are interim, or may undergo changes, if proven. For this, NTA gives candidates the opportunity to file for objection against one or more questions or answer keys of NEET, by paying a fee of INR 200 per question. NTA also releases candidates' OMR sheets along with the provisional NEET answer keys which can also be challenged. After reviewing the submitted challenges or objections, NTA releases the final answer keys of NEET, which forms the base of computing NEET result. NEET final answer keys are absolute and there is no further opportunity given to challenge against the final answer keys. While the NEET provisional answer keys are available to candidates alongwith the OMR sheets after logging in with their registration credentials, the NEET final answer keys are released on the official websites of NEET and NTA and is available for public viewing.
