There are generally four Sets of NEET question papers, which are further segregated into six parts. However, in NEET 2025, there were four sets of the NEET question paper, which were named as 45, 46, 47, and 48, and these were not further divided into six subsets, which was followed till the previous year. The names of the NEET 2024 question paper Sets and codes are Q, R, S and T. For the NEET 2024 re-exam, the question paper sets were A, B, C and D. The multiple Sets and codes in the NEET question papers ensure that there is no malpractice in the conduct of the exam. The names of the Sets and codes of the regional NEET question papers are different from the English ones. While distributing the question papers of NEET invigilators had to ensure that they did not give the same set of question papers to two consecutive candidates. Once candidates are given the NEET question paper by invigilators, they need to check whether the question paper and test booklet, or answer sheet, is of the same code. In case of a mismatch, they need to bring the matter to the invigilator's notice. In case they submit the NEET test booklet with a different code from that of the NEET question paper, their exam will stand cancelled.
No, the NEET exam or NEET question paper does not have any optional questions. Although there used to be 20 optional questions in total in between the years 2022 and 2024, but 2025 onwards, the optional questions in NEET were removed as part of the revision or change in the NEET exam pattern as per the pre-COVID era. Hence, the NEET 2025 question paper will not carry any optional questions, and will have 360 mandatory questions from Physics, Chemistry and Biology.
No, the National Testing Agency (NTA) does not release NEET answer keys and question papers together. While releasing the NEET provisional result, NTA releases candidates' OMR sheets. The final NEET answer key is released in the form of a single PDF document, carrying the keys for all sets of the NEET question papers. The hardcopy of the NEET question papers are given by NTA on the day of the exam. Being a paper-pencil based test, candidates are allowed to carry the question papers outside the exam hall. In general, NTA releases the NEET question papers of previous years on its official website few months after the exam is conducted. NTA has released the NEET 2023 question papers of English and Hindi languages. However, the NEET 2022 question papers are not available on the official website yet. It is expected that the question papers of NEET 2022 will be released soon.

You can choose any exam centre of NEET if you have opted for English medium question paper. English is available at all centres across the country. English is a universal language and the NEET question paper medium. The exam city selection option becomes limited once candidates choose a regional language, except Hindi. Apart from the medium of the question factor, the other factor that plays a role in the NEET exam centre city selection is the permanent and present address selected by candidates during the application process.
