Hello Aspirant,

NEET has a total of (200 questions) 180 questions to be attempted at totalled at a score of 720 marks i.e., four marks per question. Attempting all questions is recommended only if you are sure of the answers, as NEET is a negative marking entrance examination. For each wrong answer one mark will be deducted from your score. If you are unsure of the answer then leave it blank as not attending the question = 0 marks which means no deductions. You can find further information in the link provided below
