Yes, NEET UG follows a negative marking system. For every correct answer, the candidate receives 4 marks. For every incorrect answer, 1 mark is deducted from the total score. If a question is left unanswered, no marks are awarded or deducted. Therefore, candidates must attempt questions carefully and avoid guessing randomly, as incorrect answers can reduce the overall score. The maximum possible score in NEET UG is 720 marks.
