Hii!
I believe you are talking about the NEET UG or PG entrance examination in your question. But, your question is not clear as to what exactly do you want to know. Kindly restructure your question and ask again including the necessary details.
Let me tell you, that the NEET UG entrance exam question paper consists of total 720 marks. Out of which 180 is for physics, 180 is for chemistry and 360 is for biology subject with 45-45 and 90 question respectively. Each question contains of 4 marks and 1 mark is deducted for wrong answer as negative marking. You need to score as per the qualifying marks to pass the exam. Each year the qualifying marks change as per different factors such as number of candidates, difficulty level of exam, number of seats available etc., For more info, refer the the following website -
