NEET Chemistry Question Paper 2025 Analysis
According to the NEET exam pattern, there will be no deduction of marks for unanswered questions. Such questions will not be taken into consideration while calculating the total marks of a candidate. Hence, if candidates are not sure about the answer of a question, it is better to leave it unattempted rather than doing a guess work, to avoid negative marking. Also, candidates are advised to revise the NEET exam sheet or OMR sheet thoroughly before submitting it to the invigilators to avoid negative marking due to silly mistakes.
NTA is the authority which creates the question paper of NEET. The questions are sent in by different professors, and NTA selects the questions for the examination. No single person is responsible for designing the question paper. Generally, the NEET question papers are set by an expert committee or panel of subject experts who later review the answer key challenges. Candidates may find questions from previous years' NEET question papers as well. This is why experts suggest solving previous years' question papers for NEET preparation.
As per the NEET exam pattern, the examination will only have objective type multiple-choice questions (MCQs). Hence, there is no possibility of having descriptive questions in NEET. Moreover, given the fact that it is an entrance exam, there is not much significance of the descriptive questions or theoritical knowledge. Each question will carry four answer options and test-takers will have to select the correct answer option and mark it on the OMR sheet.

According to NEET pattern, the question paper for the candidates who have chosen Hindi as the medium will be bilingual. The second language of the question paper will be English. In case candidates have any doubts regarding a particular question or term, they can refer to the English questions. Candidates choosing the NEET question paper medium as Hindi must ensure that they have received the Hindi language question paper in the exam hall. In case they receive English or any other regional language question paper, they must report the matter to the invigilator and get it changed immediately. In case they start solving the NEET question paper of a different language and report it later, it may be considered redundant.
