Understanding the Answer Key Process
The first answer key released by the NTA is called 'provisional'. This key provides the correct answers to all the questions asked in the exam. It is not the final version. Students get a chance to look at these answers and check them.
If a student thinks that any answer in the provisional key is wrong, they can 'challenge' it. This means they can raise an objection and provide proof to support their claim. The NTA will open a special window on its website for a short time to allow these challenges. Students will need their login details to submit any objections.
After the objection period ends, a team of experts will carefully review all the challenges. If an objection is found to be correct, the NTA will make the necessary changes to the answer key. Once all changes are finalized, the NTA will release the 'final' answer key. The final results of the CSIR NET 2025 exam will be prepared based on this final, corrected answer key.
